Liverpool kept their first home clean sheet of the English Premier League season in a 2-0 win over Watford as Mohamed Salah's double rescued the off-key Reds. (More Football News)
The manner in which Jurgen Klopp's men can win when out of sorts must be hard to swallow for second-placed Leicester, who drew 1-1 at home to Norwich City, and third-placed Manchester City, who travel to Arsenal on Sunday.
Chelsea failed to put pressure on the top three as they succumbed to a 1-0 home defeat to Bournemouth, but Sheffield United moved up to fifth after brushing Aston Villa aside in a 2-0 win.
Chris Wood's goal was enough to bring Burnley's three-match losing streak to an end and condemn Newcastle United to a first defeat in four league outings.
Watford make Reds work for 16th straight home win
New manager Nigel Pearson left Anfield with every reason to be proud of his Watford side's performance on an afternoon when the Hornets had enough chances to claim a shock victory against the Premier League leaders.
Abdoulaye Doucoure and Etienne Capoue were guilty of wasteful finishing that let Liverpool off the hook and Salah made Watford pay in spectacular style.
The Egypt international curled a spectacular opener into the top corner after 38 minutes and then wrapped up a hard-fought win with a cheeky tap-in in the last minute.
The satisfaction Jurgen Klopp took from an ugly win was dulled by an injury to Georginio Wijnaldum, who suffered a muscle strain that looks set to rule him out of Liverpool's trip to Qatar for the Club World Cup.
Liverpool have now won 16 straight home Premier League games, with their lead up to 10 points.
Four defeats in five for Lampard's Blues
Bournemouth arrived at Stamford Bridge in the midst of a five-game Premier League losing streak but emerged with all three points after Dan Gosling's late goal clinched a surprise 1-0 victory over Chelsea.
Any hopes the Blues had of a return to strong domestic form following their 2-1 midweek victory over Lille began to fade as chances went begging while Bournemouth grew in confidence.
As the Cherries piled forward, Jefferson Lerma's looping header into the box six minutes from time found Gosling unmarked and he lifted the ball over Kepa Arrizabalaga and over the line.
Chelsea had 18 shots at goal throughout the match but failed to force an equaliser and Frank Lampard's men trudged off the field with a record of one win and four defeats in their last five Premier League outings.

Foxes come up short as winning streak ends
Teemu Pukki's third goal in four Premier League matches gave Norwich City the lead at King Power Stadium, where Leicester City's eight-match Premier League winning streak came grinding to a halt.
The Finland international fired Norwich ahead after 26 minutes, but their advantage did not last long, with Tim Krul palming Jamie Vardy's header into his own net seven minutes before half-time.
Daniel Farke's Norwich fought hard for their share of the points in a second half that saw Leicester heap pressure on their goal, attempting 12 shots on goal.
Ben Chilwell's cross forced a late corner from which substitute Harvey Barnes fired agonisingly wide for the hosts, who remain second in the table.
The points are shared, and our winning run comes to an end.#LeiNor— Leicester City (@LCFC) December 14, 2019
Blades up to fifth after victory over Villa
Any doubts over which of this season's promoted sides has the best chance of a top-half finish appeared to be resolved at Bramall Lane, where Fleck scored both of Sheffield United's goals in a 2-0 win over Aston Villa.
Chris Wilder's men have proved themselves extremely tough to beat and Villa's hopes of inflicting what would have been only United's second defeat in 10 league games suffered a blow when Scotland international Fleck finished a neat passing move with a goal after 50 minutes.
Fleck coolly slotted home his second 23 minutes later before Jack Grealish hit the crossbar with a penalty, leaving Villa winless in four Premier League matches and in trouble towards the foot of the table.
