Manchester City made it 13 wins from 15 Premier League games this season with a 2-1 victory at Watford on Tuesday.

Goals in each half from Leroy Sane and Riyad Mahrez secured all three points for the champions, who were again without the injured Sergio Aguero and left the in-form Raheem Sterling on the bench at Vicarage Road.

Abdoulaye Doucoure had them worried in the closing stages after Fabian Delph lost possession near his own penalty area, but City soaked up the late pressure to hold onto the lead.

The result puts City five points ahead of second-place Liverpool, having played a game more, and means Watford have now lost seven matches in a row against Pep Guardiola's side.

Ben Foster did superbly to deny Mahrez and stop Bernardo Silva and David Silva from following up on the rebound, but Troy Deeney spurned Watford's best opening of the first half when he failed to beat Ederson's outstretched leg from eight yards out.

Sane punished that miss five minutes before the break, turning home Mahrez's curling cross from the right with his chest after Foster had thwarted David Silva moments before.

It was a goal that seemed to sap some life out of the home fans and any hope of a comeback was seemingly quashed six minutes after the break, when Mahrez swept home Gabriel Jesus' cross when unmarked in the box.

Jesus wasted two clear chances for a third, heading Bernardo Silva's flick-on over the crossbar before clipping a tame finish wide of the right-hand post, but they were not left to rue those misses despite Doucoure scrambling the ball home with six minutes left.

What does it mean? City put pressure back on Liverpool

City were left to endure a nervy climax to a match that for so long had been comfortable, and it means they again have a healthy advantage over Liverpool in the table ahead of the Reds' game with Burnley on Wednesday.

Guardiola will be pleased to have been able to rest the likes of Sterling and Aymeric Laporte, too, with captain Vincent Kompany getting only his fourth Premier League start of the season.

Watford drop to 11th, courtesy of Brighton and Hove Albion's win over Crystal Palace, and Javi Gracia will be a little concerned that they have mustered only one point since October.

Mahrez a real menace

Mahrez was causing problems with his right-wing delivery long before he set up Sane to open the scoring, and he fully deserved to be on the scoresheet for a lively display, even if he was sometimes guilty of over-playing. A good Foster save denied him a second goal.

Success is hard to come by

The game largely seemed to pass by Isaac Success, who appeared uncertain when to drop deep to bolster the midfield and when to support Deeney. Mostly, he failed to do either. He also completed just 50 per cent of his passes.

What's next?

City are in London next Saturday when they visit Maurizio Sarri's Chelsea, while Watford head to Everton next Monday.
