The 175th Manchester derby pits a United side unbeaten in 40 home games in all competitions against a City side who have not lost this season in the Premier League.

Pep Guardiola&#39;s City currently lead by eight points from United in the standings, giving the game much more significance than just local pride.

Here are five big issues that will go a long way to determining the outcome of Sunday&#39;s clash at Old Trafford:

Will Mourinho &#39;park the bus&#39; at home?&nbsp;

United manager Jose Mourinho received plenty of criticism for the negative way his team approached rivals Liverpool at Anfield in October&#39;s goalless draw.

But defending in numbers and attacking on the break is also an approach that can work well for United. Relying on the counter-attack certainly paid off handsomely in the 3-1 win at Arsenal last Saturday, even if United keeper David de Gea had to make a string of saves to keep his side in front.

United are at home, but given City&#39;s ability to dominate possession, the game may, tactically at least, be more like an away match for Mourinho&#39;s team.

City have produced more passes than any other team in the league this season while United are ranked seventh in that area and it would be no surprise if Guardiola&#39;s side enjoy most of the ball.

In recent weeks, United have switched to playing with a three-man defence which allows Antonio Valencia and Ashley Young to attack down the flanks - an attacking formation which matches that of City.

But the loss to suspension of central midfielder Paul Pogba may tempt Mourinho into a more defensive line-up in the centre of the field as he looks to counter the influence of City&#39;s key creative midfielder Kevin De Bruyne.

Who will dominate the flanks?

City are great at keeping the ball in the tight spaces in midfield and United, with Serbian enforcer Nemanja Matic expected to be fit, will look to crowd the centre of the park and give De Bruyne and David Silva little room to exploit.

But the key areas are likely to be out wide where City have the speed and skill of Leroy Sane and Raheem Sterling allied with the threat from their wing-backs - Kyle Walker on the right and Fabian Delph on the left.

United match-up well in that area - Valencia was brilliant going forward against Arsenal and can work up and down the right tirelessly, while Young on the left has been one of the biggest positive surprises of the campaign so far for Mourinho.

Anthony Martial, or if preferred Marcus Rashford, have a tendency to play much wider than the typical support striker and that might limit Walker&#39;s desire to push forward, lest he leave space behind for United to exploit. If Juan Mata is chosen to replace Pogba, he could offer another wide threat on the right.

Whichever wingers and wing-backs come out on top is going to have a huge impact on the outcome.

Can United stop De Bruyne?

The stats tell the story. No-one has had more touches of the ball this season in the Premier League than the Belgian. De Bruyne also shares, with team mate David Silva, the most assists with eight so far.

Brilliant with both feet and capable of running at a defence from deep and also delivering the killer pass to City&#39;s deadly strike force, De Bruyne has been fundamental to the success of Guardiola&#39;s team.

United have in Matic, however, a player who could certainly do a close-marking job but that would rob Mourinho of the Serb&#39;s overall role of marshalling the midfield and protecting the defence. It could be a job for Ander Herrera or Marouane Fellaini.

Will Lukaku deliver when it matters most?

The former Everton forward scored 11 goals in his first 10 appearances for United but has managed just two in his last 12 and while Zlatan Ibrahimovic is fit, Mourinho is unlikely to drop his main striker for the derby.

The big trouble with Romelu Lukaku is that he has struggled throughout his career when facing the top teams. He failed to score against Arsenal, Chelsea, Tottenham and Liverpool this year and since 2014/15 he has only scored five goals in 39 games against the &#39;big six&#39;.

The Belgian could put all those doubts to bed with a winner against City. But if he misses chances, Mourinho may well turn to the fit-again Swedish great on his bench.

Pep Guardiola's City currently lead by eight points from United in the standings, giving the game much more significance than just local pride.

Football: Four big questions ahead of the Manchester derby

There have been few Manchester derbies with as much on the line as Sunday&#39;s meeting at Old Trafford of the top two teams in the Premier League -- the most anticipated clash of the campaign so far.

Pep Guardiola&#39;s City have built an eight-point lead following an unbeaten start to the season that has included 13 straight victories - equalling the record for the longest winning run in a single Premier League campaign.

Not to be completely outdone, however, Jose Mourinho&rsquo;s Manchester United have equalled a historic club record by remaining unbeaten at Old Trafford for 40 matches in all competitions.

And with former Barcelona boss Guardiola and ex-Real Madrid manager Mourinho having developed a fierce rivalry during their time together in Spain, Sunday&#39;s meeting promises to be one to savour.

The last team to beat United at home were City in September, 2016 and a repeat performance would leave the club, once derided as &quot;noisy neighbours&quot; by former United boss Alex Ferguson, 11 points clear at the summit.

City have been playing some exhilarating football this campaign with coach Guardiola&#39;s style of play, which served him so well at his previous clubs, bringing the expected rewards after a disappointing lack of consistency last season.

Yet while United have suffered two defeats on the road - to Huddersfield Town and Chelsea - they too have looked like champions at home.

The 40 games unbeaten have included 29 wins and 11 draws with 85 goals scored and just 17 conceded.

This season&#39;s Premier League record at Old Trafford is played seven, won seven - 20 goals for and just one against.

Mourinho, however, will be without his key French midfielder Paul Pogba, who starts a three-match ban following his red card in Saturday&#39;s crucial 3-1 win at Arsenal.

United have produced their best football when they have had Pogba and Serbian anchorman Nemanja Matic on the field together and the former Juventus midfielder will be sorely missed.

Given the gap between the two clubs in the table, it will be intriguing to see if Mourinho maintains his habit of playing defensively against title rivals, a tactic which has been much criticised following the goalless draw at Liverpool in October.

Pogba, however, says United will approach the game in a positive fashion.

&quot;We want to win. We need to win as well. They need to win because they know that we are behind and we are closing and closing,&quot; he said.

&quot;If I didn&#39;t believe that (we can win it), I&#39;d stop playing football now,&quot; he added.

United&#39;s Swedish striker Zlatan Ibrahimovic should be fit to feature at some stage in the game but defender Eric Bailly remains sidelined.

Football: Stakes are high in Manchester derby

Marouane Fellaini was sent off for brainlessly headbutting Sergio Aguero in an otherwise forgettable 0-0 draw between Champions League qualification rivals Manchester United and Manchester City on Thursday.

Booked for tripping Aguero in the 84th minute, Fellaini fouled him again seconds later and then blatantly butted the Argentinian, leaving referee Martin Atkinson no option but to send the Belgian off.

City remain fourth, a point behind third-place Liverpool with a game in hand, with United -- who also have a game in hand on Jurgen Klopp&#39;s side -- a point further back in fifth place.

&quot;We were the better team in the first half, they were the better team in the second half,&quot; said United manager Jose Mourinho.

&quot;They had more of the ball, more chances, but my players were amazing the way they fought.

&quot;Marouane Fellaini is frustrated. He says that with another player, it would probably not be a red card.&quot;

While United are now unbeaten in 24 Premier League games, equalling the club record, the Etihad Stadium stalemate means City retain the upper hand in the push for a top-four finish.

But despite controlling the game, City came no closer to scoring than an early Aguero effort that hit the post, while substitute Gabriel Jesus had an injury-time header disallowed for offside.

City also lost goalkeeper Claudio Bravo to an apparent calf injury, sustained as he caught a high ball, with Willy Caballero taking his place for the last 14 minutes after Bravo was stretchered off.

&quot;They created two clear chances and I am satisfied,&quot; City manager Pep Guardiola told BBC Sport.

&quot;We all have tough games coming up now and we know it&#39;s not an option to not win these games.&quot;

City remain on course for a top-four finish, their last remaining objective after last weekend&#39;s FA Cup semi-final loss to Arsenal consigned Guardiola to his first trophy-less season as a coach.

United could yet qualify for the Champions League by winning the Europa League.

But in the main, Thursday&#39;s drab derby served to illustrate why the Manchester rivals are squabbling over fourth place rather than fighting for the title.

Etihad erupts&nbsp;

With Paul Pogba injured, Mourinho aligned a conservative midfield trio of Michael Carrick, Ander Herrera and Fellaini, setting the tone for a tetchy, attritional contest.

Marcus Rashford returned in one of four changes and while his lightning pace enabled him to leave Nicolas Otamendi for dead repeatedly, the teenager cut an isolated figure.

The football that managed to emerge above the midfield melee was almost all City&#39;s.

The hosts hit the woodwork in the ninth minute, Aguero cushioning a volley against the base of the right-hand post from Kevin De Bruyne&#39;s right-wing cross.

United goalkeeper David de Gea fielded curlers from De Bruyne and Aguero and saved at his near post from Aleksandar Kolarov, while Aguero and Raheem Sterling arrowed shots over the bar.

But there were two moments of unease in the hosts&#39; box, the first when Bravo clawed Anthony Martial&#39;s cross into the path of Henrikh Mkhitaryan, whose shot he was then obliged to block.

Shortly before half-time, Rashford&#39;s free-kick from the left found Herrera unmarked at the back post, but the Spaniard headed wide.

City continued to force the issue after the break, but United, expertly marshalled by Eric Bailly and Daley Blind, kept them at bay.

De Gea comfortably saved from Sterling, twice, and Aguero, while De Bruyne ruffled the side-netting with a low drive after cutting in from the left.

Otamendi looked poised to break the deadlock when he rose to meet Kolarov&#39;s corner, but Bailly diverted his header over the bar.

Fellaini&#39;s dismissal gave City the edge and Guardiola immediately introduced Jesus, back from a broken foot sustained in February.

The Etihad erupted when the Brazilian headed in Aguero&#39;s cross, but an offside flag silenced the home fans and a stretching Aguero could only volley wide from De Bruyne&#39;s cross moments later.

A depleted Manchester United dug their trenches while the blue half of Manchester attacked relentlessly only to draw blank in final third
