Watford vs Man City LIVE: Premier League result, final score and reaction

41 mins: Ziyech drifts inside the West Ham box as Chelsea look to hit back but Dawson makes a big block to deny his shot at goal.

Lanzini sends Mendy the wrong way with a composed penalty into the side-netting, and West Ham are level!

But that was such a needless penalty for Chelsea to conceded. Jorginho’s backpass was underhit and Mendy’s touch invited pressure from Bowen and Rice. Bowen was able to step across the Chelsea goalkeeper who caught the West Ham forward as he tried to slide in.

38 mins: Nightmare for Mendy as he hauls down Bowen!

35 mins: Rudiger is able to carry the ball forward and looks to curl a shot at goal, which Dawson blocks to some murmers of frustration from the West Ham fans. It’s all a bit too easy for Chelsea at the moment. Loftus-Cheek then shifts the ball along to Mount, who found himself in space, but his low drive was gathered by Fabianski.

32 mins: Chelsea again threaten down the right and West Ham are forced into two last-ditch clearances to deny Havertz from steering a shot at goal from point-blank range. Alonso then gets down the left wing and a combination of Dawson and Diop clears as Havertz stole in at the front post.

Chelsea have lifted their tempo following Thiago Silva’s breakthrough.

29 mins: Off the line! West Ham almost hit back straight from kick-off. The ball sits up nicely for Coufal who drives a volley back across goal. Mendy looked beaten by Silva read the danger and got back to hook it clear!

Chelsea take the lead through a corner - and David Moyes will be fuming! It’s a poor goal for West Ham to concede. Mount’s cross from the right is directed into the middle of the box and Thiago Silva is able to evade Antonio to guide a downwards header inside the post.

25 mins: Chance! When Chelsea get the ball out to James in space, it usually results in some danger. The wing-back has time to get the ball out of his feet and pick out Havertz in the box, who positioned himself in between Diop and Dawson. It’s a free header for Havertz but it’s straight at Fabianski. Even if it was either side of him, it probably didn’t have enough power behind it to beat the goalkeeper.

22 mins: After sitting back for much of the match so far, West Ham press a loose touch from Jorginho as Bowen, Lanzini and Rice close him down. The Italian slips as he tries to turn away from Rice and gathers the ball in his arms believing he was fouled. The free-kick instead goes against Jorginho, who can’t believe it and is booked for his protest.

19 mins: There’s another brief moment of panic in the Chelsea box as the ball breaks to Dawson from the corner, after the visitors failed to make the first contact on the inswinging delivery. Dawson flicks an effort towards goal but it’s comfortably saved by Mendy.
