Liverpool moved back into the top four, above Manchester City, who visit Bournemouth on Monday, and Manchester United
The jet-heeled Sadio Mane scored a quick-fire brace as Liverpool revitalised their Premier League campaign with an impressive 2-0 win over Tottenham Hotspur at Anfield on Saturday.
Senegalese flier Mane netted twice in three first-half minutes as Jurgen Klopp's team claimed a first league win of 2017 at the sixth attempt and ended Spurs' nine-game unbeaten run.
Liverpool moved back into the top four, above Manchester City, who visit Bournemouth on Monday, and Manchester United, who briefly climbed above them after beating Watford 2-0.
Tottenham remain second, but they are now level on points with Arsenal after Alexis Sanchez scored twice to earn Arsene Wenger's side a much-needed 2-0 victory over Hull City.
Spurs' setback means Chelsea can move 12 points clear at the summit if they win at Burnley on Sunday.
While the title seems destined for Stamford Bridge, the battle for positions below Chelsea could not be more tight, with two points separating Spurs in second and United in sixth.
Liverpool badly missed Mane during his time at the Africa Cup of Nations with Senegal and he gave a dazzling display of his qualities with two goals in the first 18 minutes at Anfield.
For the first goal, in the 16th minute, he raced onto Georginio Wijnaldum's pass before lifting a shot past Hugo Lloris.
Two minutes later he made it 2-0 with his 11th goal of the season, sparking a raid on the Spurs box by robbing Eric Dier and then slamming in after Lloris had saved from Adam Lallana and Roberto Firmino.
At the Emirates Stadium, Sanchez brought the under-fire Wenger some breathing space as Arsenal overcame third-bottom Hull.
The Chilean forward contentiously scored with his hand in the 34th minute and netted a stoppage-time penalty after Sam Clucas had been sent off for handball to take his tally for the campaign to 17 goals.
It got Arsenal back to winning ways following successive defeats by Watford and Chelsea and left them in third place, nine points behind Chelsea.
Wenger dismissed a claim by former Arsenal striker Ian Wright that he had admitted his time at the club was coming to an end.
"I didn't give any indication about my future," Wenger told reporters.
"You know I appreciate very much that you want me to rest, absolutely. But I am not ready for that yet."
United closed to within a point of the Champions League places by beating Watford, Anthony Martial marking his return to the starting XI by scoring and setting up the opener for Juan Mata.
Jose Mourinho's side have now gone 16 league games unbeaten and while they remain sixth, they are just a point below both Liverpool and City.
"Martial deserves the chance," Mourinho told the BBC. "He has worked harder than ever in the last two weeks in the way I like: silence, but hard."
He added: "In the first half the football was fabulous. When I got the job, they were saying at Manchester United you need to play football in a certain way and I agree."
Seventh-place Everton squandered a chance to close on the teams above them after being held to a 0-0 draw at sixth-bottom Middlesbrough.
Sunderland remain bottom of the table after Southampton's new Italian striker Manolo Gabbiadini scored a slick brace in a 4-0 win at the Stadium of Light.
Jason Denayer also put through his own goal before Shane Long completed the scoring in added time.
Second-bottom Crystal Palace were also beaten, Joe Allen scoring in the second half to give Stoke City a 1-0 win that saw Mark Hughes's team climb to ninth.
Gareth McAuley was credited with a stoppage-time equaliser for West Bromwich Albion in a 2-2 draw at West Ham United.
After Nacer Chadli put West Brom ahead in the fifth minute, West Ham hit back through Sofiane Feghouli and Manuel Lanzini, only for McAuley to get a decisive touch to Jonny Evans's header at the death.
