Novak Djokovic suffered defeat in a thriller against an inspired Dominic Thiem at the<a href="https://www.wionews.com/sports/atp-finals-federer-up-against-it-after-thiem-defeat-261316"> ATP Finals </a>on Tuesday and now faces a showdown with great rival Roger Federer to decide who will reach the last four at the season-ender.

Swiss Federer shrugged of defeat by Austria's Thiem in his opening group match to comfortably beat Italian Matteo Berrettini 7-6(2) 6-3 in the day's opening singles.

But the real drama at The O2 arena came later when Thiem beat Djokovic 6-7(5) 6-3 7-6(5) in the standout match of the tournament so far.

World number five Thiem blazed 50 winners in a sensational display of aggressive hitting to claim his second group win and seal his first semi-final in his fourth appearance.

Whatever his result against the already-eliminated Berrettini the Austrian will progress, but the only victory will do for Djokovic and Federer as they clash for the 49th time and first since Djokovic won an epic Wimbledon final in July.

While Federer is trying to avoid only his second group stage exit in 17 appearances at the year-ending showpiece, the stakes will be even higher for Djokovic.

Defeat would not only halt his bid to equal Federer's six titles but would also mean he cannot end the year ranked number one. Djokovic must reach at least the final to overhaul Rafael Nadal and equal Pete Sampras's feat of finishing a year ranked number one on six occasions.

He will have to recover quickly after being stretched to breaking point by Thiem in a match lasting nearly three hours.

"We go head to head with Roger. The winner goes to semis. Loser doesn't qualify. As simple as that," Djokovic, who led 4-1 in the final-set tiebreaker against Thiem, told reporters.

Thiem responded to losing a high-quality opening set in stunning fashion, ripping winners all over the blue court to take the second set and move a break ahead in the decider.

Few players know how to weather a storm quite like Djokovic though and when he broke back and had Thiem serving at 4-5, 30-30 it seemed he was closing in on victory.

He thought he had reached match point when Thiem's rasping forehand winner was called out but the Austrian challenged and Hawkeye ruled the ball had shaved the line.

Thiem broke in the next game but again Djokovic hit back to drag the match into a tiebreak.

Djokovic led 4-1 but Thiem would not be denied and reeled off five points in a row to give himself two match points.

Thiem thought he had served an ace at 6-4 but it was called out and this time his Hawkeye challenge was unsuccessful.

However, the Austrian made sure at the second time of asking as a weary Djokovic netted.

Generous in defeat, Djokovic said: "I thought he deserved to win. He just played very courageous tennis and was just smacking the ball. He went for broke.

"It was amazing. I have played him before. I know his game. But what he did tonight was just out of ordinary."

The 26-year-old Thiem is the first Austrian to reach the semi-finals of the tournament.

Federer was pushed hard by Berrettini in the first set as the Italian powerhouse showed the kind of form that has propelled him into the world's top 10.

But once Federer changed gear to claim 10 of 11 points to breeze through the first set tiebreak and break to love at the start of the second his 58th victory at the tournament was never in doubt. The 38-year-old's thoughts then turned to Djokovic.

"We'll find out, but I think it's all flushed away from my side," the 20-time Grand Slam winner said when asked if the memory of his Wimbledon loss to Djokovic was still bitter.

"I think we both can take away some confidence from the match. Him obviously a lot. Me maybe a tad bit less.

"But at the end of the day, I didn't hope I was never going to play him again. Actually, it's good for me to play him again, and maybe that all helps to get a chance to get him back or whatever it is. Personally, excited to play Novak on Thursday."

ATP Finals: Federer eyes Djokovic after rebounding against Berrettini

Stefanos Tsitsipas celebrated victory over fellow ATP Finals debutant Daniil Medvedev like he had won the title on Monday as he finally snapped a jinx against his Russian bogeyman.

Tsitsipas, the first Greek player to qualify for the season-ender, had lost all five previous matches against Medvedev but he turned the tables in impressive fashion.

His 7-6(5) 6-4 win leaves the swashbuckling 21-year-old well-placed to challenge for a place in the semi-finals and the fact that he beat U.S. Open runner-up Medvedev appears to have made his O2 Arena bow extra sweet.

With contrasting styles and feisty demeanours both are tipped to win Grand Slam titles and the fact there appears to be 'bad chemistry' between them bodes well for the box office.

"It means more than extra. It's a victory that I craved for a long time now, and it's great that I came in at this moment," world number six Tsitsipas, told reporters.

"He's a tough player. He's a very difficult player to face. He's not giving you an easy time when you're out on the court. So it definitely means a lot."

Medvedev, 23, went on an incredible streak after Wimbledon this year, reaching six successive finals including at Flushing Meadow where he extended <a href="https://www.wionews.com/sports/atp-finals-alexander-zverev-tastes-first-victory-over-rafael-nadal-261539">Rafael Nadal</a> in a five-set thriller.

His form has cooled since then and although he raised his level against Tsitsipas the momentum was always with the Greek whose free-flowing, all-court style proved popular with the large afternoon crowd in London.

Playing the more adventurous tennis, Tsitsipas earned a set point in the opening tiebreak with a nerveless volley onto the sideline and converted when Medvedev netted a forehand.

World number four Medvedev saved three break points at 3-3 in the second but an error of judgement at 4-4 gave Tsitsipas another break point chance which this time he converted.

Tsitsipas claimed victory with a smash.

Medvedev played down suggestions that losing to Tsitsipas for the first time stung more, saying he was happy with the way he played after some poor form in the lead-up.

"He was better today, but I felt like I was missing some things," Medvedev said. "That would frustrate me against any other opponent. Of course, I wanted to make it even bigger head-to-head, but it's the way it is."

With fans and media craving new rivalries to carry the game forward when the sun sets on the golden age of <a href="https://www.wionews.com/sports/atp-finals-federer-up-against-it-after-thiem-defeat-261316">Roger Federer</a>, Nadal and Novak Djokovic, it is understandable that any potential bad blood between players is seized upon.

Tsistipas was asked outright why he does not like Medvedev.

"That's a strong statement, I never said I don't like him," he said before describing an incident in a match against Medvedev in Miami last year when words were exchanged.

"I mean, our chemistry definitely isn't the best that you can find on the tour," he said. "It just happens with people that it's not that you can just like everyone.

"It's not that I hate him. I guess as he said, we will not go to dinner together. I respect him, for sure."

Later in the Andre Agassi group world number one Rafael Nadal faces defending champion Alexander Zverev.

ATP Finals: Tsitsipas gets win he craved over Medvedev

It proved quite a day for ending losing streaks at the <a href="https://www.wionews.com/sports/atp-finals-djokovic-thrashes-berrettini-thiem-stuns-federer-261312">ATP Finals </a>on Monday as Alexander Zverev tasted a first victory over Rafael&nbsp;Nadal&nbsp;after Stefanos Tsitsipas got the better of Russian bogeyman Daniil Medvedev.

Both Zverev and Tsitsipas walked out on the huge O2 Arena with 0-5 career records against their opponents but they turned the tables with a couple of dazzling displays.

Tsitsipas beat Medvedev 7-6(5) 6-4 before Germany's Zverev, the surprise title winner last year, thumped an out-of-kilter&nbsp;Nadal&nbsp;6-2 6-4 to seal a rare hat-trick.

He might not have won a Grand Slam title yet but after beating <a href="https://www.wionews.com/sports/atp-finals-federer-up-against-it-after-thiem-defeat-261316">Roger Federer</a> and Novak Djokovic in the semi-final and final last year, he opened his defence by outplaying&nbsp;Nadal.

The Spaniard, who took his major haul to 19 this year, has a patchy record at the tournament. He has never won the title, appeared only eight times despite qualifying on 15 occasions and on his last visit, in 2017, withdrew injured.

The world number one refused to blame an abdominal strain picked up this month in Paris for his poor showing.

"It was not a problem with the abdominal at all," the 33-year-old&nbsp;Nadal, who will face Medvedev in his second round-robin match in a repeat of the US&nbsp;Open final, told reporters.

"I did not feel pain. We can find reasons or excuses, but at the end of the day, all that really matters is I need to play much better in two days.

"I needed my best competitive spirit today, and I was not there in that way."

Zverev, 22, has salvaged what initially looked like being a poor year with a late-season flourish to qualify for the showpiece and he produced a confident display to dominate.

Serving regularly at 140mph and crunching angled groundstrokes, he gave&nbsp;Nadal's abdominals a thorough workout.

He took control by breaking in the fifth game and repeated the feat two games later when&nbsp;Nadal&nbsp;blazed a wild forehand wide.

Some scintillating net play earned the German another break at the start of the second set. He stayed rock solid thereafter, not giving&nbsp;Nadal&nbsp;even a sniff of a chance to make a comeback.

"It is obviously great," said the world number seven. "Everyone knows how much I have struggled the whole season. It means so much to be playing here again where I won my biggest title last season. It means everything to me."

In terms of&nbsp;Nadal's hopes of sealing the ATP year-end top ranking for a fifth time, nothing has changed.

He arrived in London with a 640-point lead over Djokovic. With 200 points for each group win, Djokovic cut that deficit on Sunday by thrashing Italian Matteo Berrettini.

Even if&nbsp;Nadal&nbsp;suffered a recurrence of the injury or lost all of his group matches, Djokovic must still reach the final to overtake the Spaniard and match Pete Sampras's record of finishing a year as number one on six occasions.

Earlier on Monday a large crowd were treated to a high-quality duel between two players seemingly destined to be vying with Zverev for the games biggest prizes.

Tsitsipas gave a swashbuckling display against Medvedev in the first opening round-robin match between two debutants since 2007 and celebrated like he had won the title, a reaction perhaps born out of past friction between the two young guns.

"It means more than extra. It's a victory that I craved for a long time now," the 21-year-old Tsitsipas, the first Greek to qualify for the eight-man tournament, told reporters.

"Our chemistry definitely isn't the best that you can find on the Tour. It just happens with people that it's not that you can just like everyone." Tsitsipas plays Zverev on Wednesday.

<a href="https://www.wionews.com/sports/tennis-djokovic-has-world-number-one-nadal-in-his-sights-at-london-finale-260669">Five-time champion Djokovic</a> can close the gap further on&nbsp;Nadal&nbsp;on Tuesday when he takes on Austrian Dominic Thiem.

ATP Finals: Alexander Zverev tastes first victory over Rafael Nadal

<a href="https://www.wionews.com/sports/roger-federer-brushes-de-minaur-aside-to-claim-record-10th-basel-title-258408">Roger Federer</a> said he had no more margin for error if he wanted to avoid an early exit at the ATP Finals after losing his opening group match to Dominic Thiem on Sunday.

The 38-year-old Swiss, bidding for his seventh title at the event but his first since 2011, struggled to handle Thiem's aggressive game as he went down 7-5 7-5.

Only once in 16 previous appearances has Federer failed to survive the group phase, in 2008, and to avoid a repeat he will have to beat Italian Matteo Berrettini on Tuesday and most probably <a href="https://www.wionews.com/sports/tennis-djokovic-has-world-number-one-nadal-in-his-sights-at-london-finale-260669">Novak Djokovic </a>on Thursday.

Djokovic, aiming to claw back the year-end number one ranking from Rafael Nadal, destroyed debutant Berrettini 6-2 6-1 in the day's opening singles match at the O2 Arena.

Thiem put constant pressure on Federer and broke at 5-5 in each set to claim his third win over the Swiss this year.

"My forecast, it's a normal tournament from here on forward," 20-time Grand Slam champion Federer, beaten by Djokovic in an epic Wimbledon final in July, said.

"Not allowed to lose anymore for me. That's how it is every week of the year for the last 20 years, so from that standpoint there is nothing new there.

"I've got to recover, I've got make sure I play better than today, and hopefully I can win that match (against Berrettini)."

The warning signs were there in Federer's opening service game which he dropped and although he hit back impressively he faltered at 5-5 when Thiem hurried him into errors.

Federer had the majority of support in the packed arena but, try as he might, he could not find his A game in the second set as Thiem again dominated the baseline rallies.

Thiem, who has flourished this year since hiring coach Nicolas Massu after a slow start to the season, broke again at 5-5 and although Federer fought hard and had a point to take the set into a tiebreak he was unable to turn things around.

"I thought he played a tough first-round performance today, and my game was probably just not good enough, and the start didn't help," Federer said.

Thiem will face Djokovic on Tuesday.

ATP Finals: Federer up against it after Thiem defeat

Novak Djokovic ruthlessly took Matteo Berrettini apart at the ATP Finals on Sunday as he began his quest to <a href="https://www.wionews.com/sports/tennis-djokovic-has-world-number-one-nadal-in-his-sights-at-london-finale-260669">reclaim the number one</a> ranking by winning his opening group match 6-2 6-1.

<a href="https://www.wionews.com/sports/roger-federer-brushes-de-minaur-aside-to-claim-record-10th-basel-title-258408">Roger Federer</a> already faces an uphill task to win the title for the first time since 2011, however, after being outplayed by inspired Austrian Dominic Thiem, losing 7-5 7-5.

Thiem had never won his opening group match in his three previous appearances but took full advantage of a unusually sluggish Federer to make a flying start.

While six-time champion Federer will fancy his chances of steadying the ship against Berrettini on Tuesday, he will likely need to beat Djokovic on Thursday to reach the semi-finals.

Only once in 16 previous appearances has Federer not survived the group stage, back in 2008.

Berrettini, the first Italian to play in the season-ending showpiece since 1978, was given a harsh lesson by 16-time Grand Slam champion Djokovic at the O2 Arena.

The 32-year-old Djokovic began the match 640 points behind Rafael Nadal in the race to end the year on top of the rankings, but victory chipped that advantage down to 440.

Djokovic must at least win two group matches and reach the final to have any chance of matching Pete Sampras's record of ending six separate years as world number one.

Spaniard Nadal, who has concerns over an abdominal injury sustained at the Paris Masters, plays his first group match on Monday against defending champion Alexander Zverev.

As an opening singles match in a tournament featuring the world's best eight players, it was a disappointing spectacle as the 23-year-old Berrettini succumbed all too easily.

The first four games were shared but once Djokovic got into his metronomic groove he looked untouchable and the errors began to flow off his opponent's racket.

Berrettini snatched at a forehand at 2-3 to gift Djokovic the break and in no time at all he was a set and 4-0 down.

Djokovic had a momentary lapse to drop serve but was in no mood to hang around as he racked up his 36th win at the event.

He did have some sympathy for his opponent though.

"I remember when I played for the first time in the ATP Tour Finals in 2007, I lost all three matches in the group," he said.

"I was tense. It's a lot of pressure mentally, that you have to deliver your best, where for us guys that have been playing on the top level for many years, we have the experience."

The evening match was much more entertaining as Thiem, runner-up at the French Open to Nadal in June for a second successive year, took his career record over Federer to 5-2.

He broke serve in the opening game and although Federer hit back impressively Thiem was the more aggressive player throughout, using his forehand to keep Federer on the back foot.

Federer buckled under pressure at 5-5 in the opener and Thiem confidently held in the next game.

It felt like Federer was just hanging on in the second but he offered up three break points at 5-5 with a volley error.

Serving for the match, Thiem missed one match point and had to save a break point as Federer dug in but he made no mistake at the second time of asking, pummelling away a forehand to seal a third win over Federer this year.

Only once in 16 previous appearances has Federer not survived the group stage, back in 2008. Berrettini, the first Italian to play in the season-ending showpiece since 1978, was given a harsh lesson by 16-time Grand Slam champion Djokovic at the O2 Arena. The 32-year-old Djokovic began the match 640 points behind Rafael Nadal in the race to end the year on top of the rankings, but victory chipped that advantage down to 440. Djokovic must at least win two group matches and reach the final to have any chance of matching Pete Sampras's record of ending six separate years as world number one. Spaniard Nadal, who has concerns over an abdominal injury sustained at the Paris Masters, plays his first group match on Monday against defending champion Alexander Zverev. As an opening singles match in a tournament featuring the world's best eight players, it was a disappointing spectacle as the 23-year-old Berrettini succumbed all too easily. The first four games were shared but once Djokovic got into his metronomic groove he looked untouchable and the errors began to flow off his opponent's racket. Berrettini snatched at a forehand at 2-3 to gift Djokovic the break and in no time at all he was a set and 4-0 down. Djokovic had a momentary lapse to drop serve but was in no mood to hang around as he racked up his 36th win at the event. He did have some sympathy for his opponent though. "I remember when I played for the first time in the ATP Tour Finals in 2007, I lost all three matches in the group," he said. "I was tense. It's a lot of pressure mentally, that you have to deliver your best, where for us guys that have been playing on the top level for many years, we have the experience." The evening match was much more entertaining as Thiem, runner-up at the French Open to Nadal in June for a second successive year, took his career record over Federer to 5-2. He broke serve in the opening game and although Federer hit back impressively Thiem was the more aggressive player throughout, using his forehand to keep Federer on the back foot. Federer buckled under pressure at 5-5 in the opener and Thiem confidently held in the next game. It felt like Federer was just hanging on in the second but he offered up three break points at 5-5 with a volley error. Serving for the match, Thiem missed one match point and had to save a break point as Federer dug in but he made no mistake at the second time of asking, pummelling away a forehand to seal a third win over Federer this year.

ATP Finals: Djokovic thrashes Berrettini, Thiem stuns Federer

Rafael Nadal has said he will travel to the ATP finals in London after undergoing a scan on an abdominal injury that forced him to retire from last week's <a href="https://www.wionews.com/sports/paris-masters-nadal-marches-on-in-paris-djokovic-also-reaches-quarters-259155">Paris Masters</a> at the semi-final stage.

"Yesterday I had a scan in Mallorca and despite having a small strain in my right abdominal, I will travel to London," the world number one said in a statement on his official Twitter account on Tuesday.

"On Thursday or Friday I will start training on my serve and my aim is to be able to play the ATP Finals in London. Thanks for your support."

Even though he withdrew from his semi-final tie with Denis Shapovalov, Nadal's run to the last four in Paris saw him reclaim the <a href="https://www.wionews.com/sports/rafael-nadal-once-again-claims-no-1-spot-in-rankings-novak-djokovic-slips-259888">number one spot</a> from Novak Djokovic on Monday.

The ATP finals take place between November&nbsp;10-17. Nadal has never won the tournament, losing in the final to Roger Federer in 2010 and Djokovic in 2013, when it was known as the ATP World Tour finals.

Tennis: Rafael Nadal to travel to ATP finals despite injury

Twenty four hours after being booed for having the audacity to take down a tennis great, Alexander Zverev returned to topple another one as he stunned Novak Djokovic to win the ATP Finals title on Sunday.

Zverev, billed as the player most likely to lead the sport into a new golden era once the holy trinity of Roger Federer, Djokovic and Rafael Nadal have hung up their rackets, took full advantage of an off-key Serb to win 6-4, 6-3.

Hamburg-born Zverev had been shamefully booed and heckled on Saturday by a Federer-worshipping crowd having beaten the six-time champion after a controversial second-set tiebreak.

Against world number one Djokovic, however, the 18,000 fans wedged into the cavernous O2 arena were roaring their support as he produced a level of tennis his opponent could not match.

He struck 20 winners to Djokovic's seven - the last of which was a backhand to end a one hour and 19-minute duel.

"I really can't describe it. It is the biggest title I have ever won," Zverev said on court after becoming the first German to win the ATP's most prestigious title - often referred to as 'the fifth slam' - since Boris Becker in Frankfurt in 1995.

In becoming the youngest ATP Finals champion since Djokovic, also 21, in 2008, Zverev sent out a clear message that he is ready to spend a considerable amount of time at tennis' top table and start accumulating the game's biggest prizes.

Djokovic, whose error-strewn display was a shock after a dominant week in southeast London which included an easy round-robin win over Zverev, sportingly walked around the net to congratulate his conqueror after match point - the German still laying on his back in a state of disbelief.

Later, Djokovic told reporters: "There's a lot of similarities in terms of trajectory of professional tennis, in our careers. Hopefully, he can surpass me.

"There's a lot of time ahead of him. (I) Wish him to stay healthy and obviously win a lot of titles."

Zverev, younger brother of Tour pro-Mischa and now coached by eight-times major champion Ivan Lendl, is yet to go past the quarter-finals of a Grand Slam.

That is still the test next year but on Sunday he displayed an added sense of maturity, to go with the natural flair and easy power that have marked him out as a future number one.

His forehand, often regarded as a weakness, was armour-plated and he showed a refreshing willingness to attack the net -- a skill he perhaps has learned from his brother.

Most impressive was that he often prevailed in the long, attritional baseline rallies in which Djokovic has used as the foundation for 14 Grand Slam titles.

The opening eight games resembled a boxing match with both players probing for weaknesses - although it was evident that Zverev's packed the more powerful punches.

Djokovic, winner of 35 of his last 37 matches during a dominant second half of the year which propelled him back to world number one, had not dropped serve all week and had faced only two break points in his four previous matches.

But at 4-4 he wavered as he yanked an edgy forehand halfway up the net to give Zverev the chance to serve for the set.

Zverev took his opportunity in emphatic fashion - blasting down three consecutive aces then winning the set when another Djokovic forehand flew long.

An increasingly-ragged Djokovic then dropped his opening two service games of the second set, either side of breaking Zverev for the first time as the German played a rare loose game.

The crowd still expected a Djokovic fight back but it never materialised and at 3-5 the 31-year-old crumbled, serving a double-fault to help Zverev earn two match points.

He saved the first but was left standing as Zverev conjured a stunning backhand to cap a brilliant display.

Watch: Why Alexander Zverev was booed during clash against Roger Federer

Alexander Zverev defeated Swiss star Roger Federer 7-5, 7-6 (7-5) in the <a href="http://www.wionews.com/sports/novak-djokovic-thumps-anderson-to-set-up-final-clash-with-zverev-177928">semis of ATP Finals</a> and became the first German tennis player since Boris Becker in 1996 to make it to the title match.&nbsp;

"Federer, who is 16 years older than 21-year-old Zverev, had been pursuing the 100th title of his illustrious career this week and now drops to 10-5 in semi-finals at the season finale, which he first won in 2003 when the tournament was played in Houston," ATP's official website stated.

Rather than being able to celebrate to reach the final of a tournament, which is often dubbed "the fifth slam", he was shamefully booed and heckled during his post-match speech.

The match ended on an unsavoury note due to an incident during the tie-beak when a ball boy dropped a ball during a rally. Zverev rightly asked for a let, but the Federer fans in The O2 crowd were unhappy that the point was replayed and booed him.

Zverev apologised to Federer but admitted he was upset about the incident.

Alexander Zverev: "Well I mean then the ball boy dropped the ball in the middle of the rally and ran for it. So, without even thinking I stopped the rally and said it was a let. You know that's how it is with the rules. "Obviously the crowd didn't appreciate it, to which I was a little bit upset.... not upset, but I was a little bit sad at the end to it."

Alexander Zverev defeated Swiss star Roger Federer 7-5, 7-6 (7-5) in the semis of ATP Finals and became the first German tennis player since Boris Becker in 1996 to make it to the title match.

Alexander Zverev defeated Swiss star Roger Federer 7-5, 7-6 (7-5) in the semis of ATP Finals and became the first German tennis player since Boris Becker in 1996 to make it to the title match. "Federer, who is 16 years older than 21-year-old Zverev, had been pursuing the 100th title of his illustrious career this week and now drops to 10-5 in semi-finals at the season finale, which he first won in 2003 when the tournament was played in Houston," ATP's official website stated. Rather than being able to celebrate to reach the final of a tournament, which is often dubbed "the fifth slam", he was shamefully booed and heckled during his post-match speech. The match ended on an unsavoury note due to an incident during the tie-beak when a ball boy dropped a ball during a rally. Zverev rightly asked for a let, but the Federer fans in The O2 crowd were unhappy that the point was replayed and booed him. Zverev apologised to Federer but admitted he was upset about the incident.

Alexander Zverev becomes first German to reach ATP Finals title match since 1996

Novak Djokovic produced a masterful display to outclass South Africa's Kevin Anderson 6-2, 6-2 on Saturday (November 17) to set up an ATP Finals title showdown with Alexander Zverev.

The world number one was immaculate from start to finish against the 32-year-old as he put himself within touching distance of a record-equalling sixth title at the year-ender.

He offered up a mere 14 unforced errors and not a single break point as he again proved too good for Anderson, who he beat to win Wimbledon this year.

"I think it was the best match I've played so far this week -- it came at the right time," Djokovic, who has been almost unstoppable in the second half of the year, said.

"Kevin has been playing great tennis this week. He lost his serve in the first game which was big because he relies so much on his serve. I tried to win as many points on his second serve as possible. It worked very well.

"I'm very happy to reach the final."

Djokovic found his range immediately and the writing was on the wall for Anderson when he dropped serve in the opening game.

Anderson, the first South African to reach the semi-finals in the tournament's 48-year history, simply had no answer to the relentless accuracy of Djokovic's groundstrokes and had to save two break points in his next service game.

Breezing through his own service games - he is yet to be broken this week - Djokovic was able to exert maximum pressure on Anderson's delivery and his opponent buckled to drop serve again as Djokovic pocketed a one-sided opener.

There was no let-up at the start of the second set for Anderson as he double-faulted to go 0-40 in his opening service game, Djokovic duly breaking again as the world number six dumped a forehand into the net.

Anderson received a code violation for an audible obscenity but it was hard to blame him for losing his cool as Djokovic continued to turn the screw.

Breaks were arriving with the frequency of London buses for the Serb and a rasping crosscourt forehand gave him another one as he romped into a 5-1 lead.

Anderson nicked one game back but it was a hopeless task and Djokovic put him out of his misery with a netcord on matchpoint to claim a 35th win in his last 37 matches -- a run including the Wimbledon and U.S. Open titles to swell his collection of Grand Slam titles to 14.

Not bad for a man who began the year plagued with an elbow injury that needed surgery and who slumped to 22nd in the ATP rankings as recently as June.

Should he win against the 21-year-old Zverev, who he beat convincingly in the round-robin stage here, the 31-year-old will become the oldest player to claim the title.

Roger Federer, the previous oldest, was beaten 7-5, 7-6(5) by Zverev in the day's first semi-final.

Novak Djokovic thumps Anderson to set up final clash with Zverev

The Davis Cup must not try to compete with the soon-to-be-launched ATP Cup and revert to its traditional home and away format, according to Swedish great Mats Wilander.

In a controversial move the International Tennis Federation (ITF) this year voted to revamp the 118-year-old team event which is known for its partisan, soccer-like crowds.

Instead of a year-long draw in which ties are played on the home soil of one of the nations involved, including the final, a week-long 18-nation event, backed to the tune of $3 billion by investment group Kosmos, will kick off in Madrid next November.

Next weekend's Davis Cup final in Lille's Stade Pierre Mauroy, where hosts and defending champions France take on Croatia, will be the last of its kind.

Wilander says the ITF should think again.

"I think the Davis Cup is in the middle of reorganising but they are not really knowing exactly what they need to do to get it back on track," Wilander, who won three finals with Sweden, told Reuters in an interview at the ATP Finals in London.

"They should not be competing with the ATP Cup.

"Davis Cup must be home and away and inspire local enthusiasts. To take away, for example, Belgium's chance to play at home in the Davis Cup semi-final and put them on neutral ground, that's crazy."

Next year's Davis Cup will still have home and away ties -- but only in the first round. The winners will go forward to the 18-nation finals played at the Caja Magica. Wilander says that is the wrong way round.

"The Davis Cup should be home and away from the semi-finals as a minimum, I would say even the quarters," he said.

"Roger Federer doesn't want to play a first round perhaps in Kazakhstan. But a semi-final in Basel, in front of 20,000 Swiss fans? Of course he will. It's detrimental.

"If David Goffin gets to the quarter-finals of the French Open some diehards in Belgium will tune in. If Belgium is playing semi-finals of Davis Cup at home, 50 percent of sports fans will tune in.

"That's what the little kid with his mum and dad remembers. I bet 50 percent of the top 100 players remember watching (the) Davis Cup before they watched, maybe not Wimbledon, but certainly before the other Slams or ATP tournaments."

Wilander says next week's final will be a massive event in France, all the more reason to leave the format alone.

"You want to take that away?" Wilander said. "France is perhaps the biggest tennis nation but they don't have much to cheer at the French Open. The Davis Cup is a chance for French players to win something big, in France."

ATP CUP HOPES

The ATP Cup, featuring 24 nations, was launched by the ATP Tour this week in London and will start in January 2020 in three Australian cities -- just before the Australian Open and six weeks after the first edition of the new Davis Cup.

"It's a brilliant idea," Wilander said. "It gives players a team competition because Davis Cup is not always convenient for the player. I hope it's a massive success."

And as for the Davis Cup's new model, Wilander said: "Maybe if it would be a failure the ITF would go back and look at it, fine tune what they had instead of changing everything."

World number one Novak Djokovic, who won the Cup with Serbia in Belgrade, said players would miss the frenzied home support.

"The home-and-away was probably the very thing that attracted all the players and fans to this competition," Djokovic, who attended the launch of the ATP Cup, said.

"At the same time in order to change something, you also need to sacrifice something. I guess for this kind of a format change, you had to take away something, and that was it."

Wilander criticises Davis Cup revamp as 'last' final looms

Shortly after German wunderkind Alexander Zverev trudged off court having lost to Chung Hyeon at this year's Australian Open he was treated to a few kind words from Roger Federer.

Whatever the Swiss great said apparently had some effect because scroll forward to the end of the year and the 21-year-old tops the Tour match wins chart with 56.

He has three titles to his name this season, including winning a third Masters 1000 in Madrid, and on Saturday he will become the first German for 15 years to contest a semi-final match at the season-ending ATP Finals.

The man he will face is none other than 20-times Grand Slam champion Federer who is chasing a seventh ATP Finals crown.

World number five Zverev, now under the watchful eye of eight-times Grand Slam champion, and former coach to Andy Murray, Ivan Lendl, does not attribute his great season to Federer's words of wisdom. But they certainly did no harm.

"That chat was more for then in that time. I was very upset about my third-round loss," Zverev told reporters after his 7-6(5) 6-3 win over John Isner to seal a last-four spot.

"I had a tough match, another tough loss at a Grand Slam. He was more talking about that, that I shouldn't get too upset. He made his first quarter-final much later in his career, as well."

Zverev, tipped to lead tennis forward in the post Federer, Novak Djokovic, Rafael Nadal and Murray era, finally reached a Grand Slam quarter-final at this year's French Open -- at the 15th time of asking. Federer did it in his eighth.

There are signs, though, that Zverev is beginning to harness his natural power and foot speed into a complete package. Beating Federer on Saturday at the 02, one of the world's biggest tennis stages, would send out a statement.

"It's going to be a very difficult match," Hamburg native Zverev, already beaten this week in group play by world number one Novak Djokovic, said.

"I mean, him on this surface, indoor court, he's an unbelievable player."

Former world number one Mats Wilander believes the appointment of Lendl could be a key decision for Zverev.

"He is going in the right direction," the Swede told Reuters. "He's made big steps in his ranking which is good and small steps in terms of his game. He is not panicking any more.

"There is still room for improvement. It won't be overnight but it's going to help him tremendously to have someone like Ivan with his experience. Lendl made just small changes with Murray and he ended up winning a bunch of majors."

Zverev acknowledged there are areas to work on.

"All of you guys keep thinking that my forehand is absolute crap, to be honest," he told reporters. "I don't know why.

"Of course, it needs improvement. But every other shot in the book kind of needs improvement."

American John Isner said it had been "very very difficult" to focus on his second match at the ATP Finals against Marin Cilic after learning of the death of his close friend and former strength coach Kyle Morgan.

Morgan, a 35-year-old former Florida University&nbsp;football&nbsp;player, was found dead on Monday after being reported missing by his family.

"Found out two nights ago after I lost to Novak (Djokovic)," Isner, 33, told reporters after his 6-7(2) 6-3 6-4 defeat -- his second loss on his debut in the tournament. "It's difficult, very difficult. Got to go out there and play.

"When I left college, I worked out exclusively with Kyle for probably seven years. That's four, five times a week for seven years. We lived together, as well.

"Certainly very close. It's devastating not just for me, but for a whole bunch of people. He was a fantastic guy."

Earlier the world number 10 had posted a message on his Instagram page, alongside a photo of the two of them.

"It's hard to explain how much I loved you and how instrumental you were in making me who I am today. My heart and everyone who knew you is absolutely broken," Isner wrote.

"You touched so many lives in the best possible way.

"Despite our crazy differences, we forged an inseparable bond. You were the most knowledgeable strength coach ever and the years we spent in the gym together allowed me to compete at the highest level.

"Kyle Steven Morgan, I love you bro. Gone but never forgotten."

Isner will face Germany's Alexander Zverev in the 02 Arena on Friday still with an outside chance of reaching the semi-finals.

Considered as one of the best football players in the world, striker Cristiano Ronaldo on Monday night found a new job of a ball kid at the ongoing ATP Finals.

Ronaldo got involved in ball kid duties while watching world number one Novak Djokovic's opening match against John Isner of America as the tennis ball bounced into the stands near the first row where he was sitting.

Pleased to see Ronaldo watching tennis, Djokovic, who was wearing black and white, jokingly said, "I had colours of his club on my attire tonight. I`m sure he was happy to see that."It is not the first time that Juventus forward has watched any professional tennis.

Last year, the football star was in attendance to watch Spaniard Rafael Nadal beat Djokovic in the semi-finals of the Mutua Madrid Open."It is great to have big football star like him, courtside watching tennis. He used to come and watch Rafa (Rafael Nadal), Roger (Federer) and myself in Madrid.

Kevin Anderson came within a whisker of a rare "double bagel" at the ATP Finals when he trounced Japan's Kei Nishikori 6-0, 6-1 at the 02 Arena on Tuesday (November 13).

The 32-year-old debutant at the ATP's blue riband event won the first 11 games of the round-robin clash before a relieved Nishikori finally got on the scoreboard with an angled winner.

Normal service was quickly resumed though as Anderson closed out victory thanks to a 24th unforced error by Nishikori.

Only six-times champion Roger Federer has enjoyed a 6-0 6-0 victory at the season-ending tournament, that coming in 2005 in Shanghai against unfortunate Argentine Gaston Gaudio.

Anderson, the first South African to qualify for the eight-man event since 1995, made it two wins from two round-robin matches with a stunning display.

What made it all the more impressive was that Nishikori had beaten Federer in straight sets on Sunday and that Anderson had trailed the Japanese 3-5 in their head-to-head record.

Anderson, who opened with a straight sets win against Dominic Thiem, tops the Lleyton Hewitt group and will reach the semi-finals if Thiem beats Federer later.

Kevin Anderson made a winning debut at the ATP Finals with a 6-3, 7-6(10) victory over Austrian Dominic Thiem in the opening singles match at the O2 Arena on Sunday.

Wimbledon runner-up Anderson, the first South African to qualify for the season-ender since Wayne Ferreira in 1995, was comfortably the better player in a one-sided first set.

The second set was a much tighter affair with serve dominating but Anderson sneaked a gripping tiebreaker 12-10 on his fourth match point, banging down his 13th ace to open his account in the Lleyton Hewitt group.

Anderson, 32, celebrated by leading the packed crowd in singing 'happy birthday' to his wife Kelsey.

Swiss Roger Federer will begin his quest for a record-extending seventh title at the eight-man season-ender when he faces Japan's Kei Nishikori in the evening session.

The opening action featured two of this year's Grand Slam runners-up but it was Anderson who looked best-equipped to make a big impression alongside the River Thames.

Standing at six foot eight, it would be easy to dismiss him as just a big server but his all-round game was too good for Thiem.

"He's very dangerous. He serves well. I think out of the taller guys, he's playing outstanding from the baseline," Thiem told reporters. "Of course, he can win the title here."

Anderson had lost both his matches against Thiem this year, having won their previous six clashes, and he looked fired up to reassert his dominance over this year's French Open runner-up, clenching his fist regularly after winning points.

He broke serve in the fourth game after a deep service return forced an error from the Austrian and had chances for a double break two games later but Thiem hung in.

Anderson wrapped up the set on serve at 5-3 but Thiem came out striking the ball with more aggression in the second set and improved his serving percentage to such an extent that he conceded only two of 25 points after landing his first delivery.

Thiem could make little impression on the Anderson serve either, though, and the match drifted into a tiebreaker.

The 25-year-old Austrian saved a match point at 5-6 before playing a sensational point to earn a set point of his own, only to then net a forehand off a powerful Anderson first serve.

World number six Anderson earned a second match point and again Thiem responded strongly, saving it with a deft volley.

Anderson fired down an ace to save a second set point and, despite failing to convert a third match point, he would not be denied. There is still time for Thiem but with Federer still to play he faces a third consecutive group phase exit.

The Gustavo Kuerten Group, featuring world number one and tournament favourite Novak Djokovic, Marin Cilic, Alexander Zverev and American debutant John Isner begins on Monday.

Anderson off to flyer at ATP Finals with win over Thiem

Novak Djokovic can now add the "Comeback Player of the Year" award to his vast collection of honours and the Serb can complete his remarkable resurgence by winning a record-equalling sixth title at the ATP Finals next week.

When Djokovic began the year outside the top 10 in the ATP rankings and battling the elbow injury that sidelined him for the second half of 2017, few imagined he would arrive for the season-ender in London back as leader of the pack.

But the 31-year-old will end the year as number one, having slumped to a 12-year low of 22 in May.

Rafael Nadal's hopes of clinging to top spot ended when he pulled out of the ATP Finals with abdominal and ankle injuries while Argentina's Juan Martin del Potro misses out with a knee injury having qualified for the first time since 2013.

Six of the world's top eight are present though including perennial London favourite Roger Federer who, aged 37, will be appearing at the ATP showpiece for the 16th time looking for a seventh title and a first since 2011.

He marked down Djokovic as the favourite during his pre-tournament news conference on Friday.

"It's really only Novak who can say 'If I play as well as I have the last three months then maybe I can win the ATP Finals as well'," the Swiss, who begins in Lleyton Hewitt group against Japan's Kei Nishikori on Sunday, told reporters.

"But that's never a given because best-of-three-set matches indoors, the margins are slimmer and it can slip fast."

Djokovic looks the man most likely to deny Federer a 100th Tour title, having resumed the dominance he displayed in 2011, 2015 and 2016.

After admitting he returned too soon from elbow surgery in February, his game clicked into gear at Wimbledon where he beat Nadal in a classic semi-final then swept past Kevin Anderson to the title.

'ULTIMATE CHALLENGE'

He posted a 22-match winning streak from Cincinatti to the Paris Masters, taking in the U.S. Open where he beat Del Potro to earn his 14th Grand Slam title and go equal third on the all-time list with Pete Sampras, behind only Nadal and Federer.

"Being (ranked) number one is probably the ultimate challenge in our sport and the pinnacle of the season," Djokovic, voted by his fellow professionals as the Comeback Player of the Year, told reporters.

"It's extra special this season because of the whole journey I've been through the past 15 months, particularly the last eight months, after surgery in February.

"Quite incredible, not just that I was ranked 22. I never thought it was impossible but I thought it might take more time. It turned out to be a perfect five months."

Djokovic heads the Gustavo Kuerten group and will begin against big-serving American debutant John Isner on Monday before tackling German wunderkind Alexander Zverev, making his second appearance, and Croatian powerhouse Marin Cilic.

Isner hopes to make a similar impact to compatriot Jack Sock, who reached the semis on his debut last year before losing to eventual champion Grigor Dimitrov.

"It means a lot to be here," Isner said. "Been pretty close throughout my career, but it never happened."

On facing Djokovic first up, he said: "I'm up against it for sure. He's had an incredible second half to the year. I don't have much to lose, so I'll play loose and free."

Anderson is the other debutant and will become the first South African in 23 years to grace the season-ender.

He opens play in Hewitt group on Sunday against French Open runner-up Dominic Thiem.

Rafal Nadal withdraws from Abu Dhabi season opener

Grigor Dimitrov stood one win away from the biggest title of his career on Saturday after ending his Jack Sock jinx to reach the final of the season-ending <a href="http://www.wionews.com/sports/atp-finals-djokovic-thrashes-goffin-picks-row-with-umpire-8965">ATP Finals</a> at the 02 Arena.

The Bulgarian, finally beginning to look the real deal after year&#39;s weighed down by comparisons to Swiss great Roger Federer, produced more dazzling tennis to win 4-6 6-0 6-3 and set up a Sunday showdown with fellow debutant David Goffin.

With Federer stunned earlier by Goffin, who Dimitrov thrashed in group play earlier in the week, the door had opened tantalizingly for the 26-year-old to go on and collect the biggest title of his career to date.

But Sock had won their last two meetings having saved match points, most recently at Indian Wells this year, and those demons were lurking for Dimitrov as victory loomed.

Poised for victory at 5-3 40-15 in the decider he made two nervy errors then ballooned a forehand out on a third match point. As proof of his greater mental fortitude these days, however, Dimitrov got the job done at the fourth attempt.

The victory means he will move above Alexander Zverev and end the year as world number three, with only all-time greats Federer and Rafael Nadal ahead of him.

&quot;I don&#39;t know what to say. This took a lot out of me,&quot; Dimitrov, the first debutant to reach the semi-finals after going unbeaten in round robin play since Andy Murray in 2008, said in court. &quot;But my belief was good today.&quot;

Asked how he had controlled his nerves when serving for the match, Dimitrov said: &quot;You have to. I was very composed and didn&#39;t let negative thoughts come to my head.

&quot;If I&#39;d have been broken in the last game then tough luck, I would have gone down the other side and played again. I&#39;m just so humbled to be able to play the final tomorrow.&quot;

Sock had gate-crashed the London showpiece by winning the Paris Masters and catapulting up the standings and became the first American to reach the semi-finals since Andy Roddick in 2007 when Shanghai was the host city.

While his journey came to a halt, the 25-year-old said he now felt like he belonged at the top of the game.

&quot;Shouldn&#39;t have been here in the first place,&quot; he said. &quot;I mean, to be here, my first appearance, to make the semis, getting through a pretty tough group, that&#39;s a big confidence booster for me.

&quot;Now I want to go and play some golf.&quot;

Tennis: Dimitrov snaps Sock jinx, rises to world number three

South Korea&#39;s Hyeon Chung kept his cool to upset top-seeded Russian Andrey Rublev and claim his first title at the Next Gen ATP finals in Milan on Saturday.

The bespectacled 21-year-old rallied from a set down to see off Rublev, the world number 37 who reached the US Open quarter-finals this year, 3-4 (5/7), 4-3 (7/2), 4-2, 4-2 in just under two hours.

Chung, ranked 54, sealed victory on his third match point after Rublev had saved two at 3-1 down in the fourth set of the final at the season-ending, eight-player tournament.

&quot;After losing the first set, and down one break in the second, I was really nervous, really angry, but I tried to have a poker face,&quot; said Chung.

&quot;I&#39;m trying to create an image of being really strong mentally and I starting playing better and better,&quot; he said.

The former student of the Nick Bollettieri Tennis Academy in Florida who turned to a mental coach to help him deal with the pressure of tennis received $390,000 dollars (335,000 euros) but no world ranking points for winning the under-21 tournament.

Chung revealed that his mind training had helped him in Milan, just days after he had suffered a first-round exit in Paris to Rafael Nadal.

&quot;The coach says all the time, first try to stay calm and in control, to have a chance to play better and better.&quot;

It was Chung&#39;s third victory over Rublev. He beat the Russian earlier in the week and also at Winston-Salem on the ATP Tour in August.

Too emotional&nbsp;

The Russian said he had let his emotions take control.

&quot;I was playing much better than him. I was dictating the match, and then just because I let my emotion out and everything changed, because Chung, he was always there,&quot; said Rublev.&nbsp;

&quot;He was always focused. He was always in the match.

&quot;No matter if something goes wrong, he was still fighting. And me, from a little thing, I just lose my control and that&#39;s it. I just lost because of my head.

&quot;Mentally he&#39;s really strong.&quot;

The sixth-seeded Chung won all three matches in group play, including a straight-sets win over Rublev, and defeated Russian Daniil Medvedev in the semi-finals.

The momentum swung his way in the third set as Rublev&#39;s frustration broke through at his inability to wear down Chung.

He becomes the first South Korean to lift an ATP World Tour singles trophy since Lee Hyung-Taik won in 2003 at Sydney.

Medvedev took third place after Croatia&#39;s Borna Coric pulled out injured from a playoff.

The ATP used the inaugural tournament to test a number of innovations with the promising young players of the season competing in the round-robin format with the first to four games in each set winning -- a tie-break is used when the scores reach 3-3.

Changes also included no line judges with all calls made using Hawk-Eye Live, no lets, sudden-death points at deuce and a shot clock to ensure a 25-second rule between points to keep play ticking along briskly.

The Spaniard pulled out of the Paris Masters before his quarter-final match against American John Isner after experiencing discomfort in his right knee during his third-round win over Pablo Cuevas.

&rdquo;Hopefully the knee is good,&ldquo; Nadal told Sky Sports. &rdquo;I&rsquo;ve done everything I&rsquo;ve needed to do in order to get ready for London... Let&rsquo;s see if I am able to be 100 per cent to compete.&quot;

&rdquo;If nothing happens, then I will play. I visited my doctors after the Paris Masters - it was a tough day for me having to pull out of Paris.

&ldquo;I know I&lsquo;m confident because I&lsquo;m having a great season with one event to go. I am here to try my best.&rdquo;
