Chelsea v West Ham latest - live Premier League updates from Stamford Bridge as Chelsea host West Ham in London Derby

Chelsea got away with that one! It ends 1-0 to Chelsea at Stamford Bridge who tighten their grip on third spot.

The deadlock is finally broken, and what a huge goal that could turn out to be for Chelsea! Alonso pulls a cross back towards Pulisic on the penalty spot, who converts excellently to give Chelsea the lead.

Jorginho with a truly terrible penalty! He just passes it to Fabianski!

What a shame. Dawson has been sent off for denying a goalscoring oppourtunity.

That won't effect his involvement in Thursday's tie.

VAR are having a look at a potential red card here...

Dawson, who has been so good today, pulls Lukaku back and Chelsea arw awarded a penalty.

He catches Soucek with his elbow and is awarded the first card of the game.

Romelu Lukaku, Christian Pulisic and Hakim Ziyech are introduced, as Havertz, Werner and Loftus-Cheek make way.

He couldn't get any force behind it! The ball drops to the striker and from close range stabs it towards goal, but Fabianski denies him!

Yarmolenko is replaced by Jarrod Bowen.

Mount drills the ball towards goal but once again Dawson is there to deny it, before Werner picks up the loose ball and fires into the side netting.

Yamolenko breaks throught the Chelsea defence, and from a tight angle stikes towards goal but Mendy makes an important save before denying the rebound too.

It's the first change of the day, and Rice comes on for Noble who has put in a good shift.

Chelsea have looked much brighter and West Ham are also a threat on the counter attack, there could be goals on the way!

The defender strikes from distance and Fabianski is called into action again to beat it away.

Kante strikes on the edge of the box and it deflects off of Johnson, which almost catches Fabianki out, but goalkeeper is able to react quick enough to catch the ball.

Just like we'd hoped, a bit of life has been injected into this game. West Ham fly forward through Yarmolenko, who cuts inside to strike but his effort is weak and is blocked by Chalobah.

West Ham are struggling to find their feet as Chelsea hit the Hammers with wave after wave of attack. They've had a few shots blocked and this is the first time Chelsea have looked like opening the scoring, but West Ham hold on for now.
