Almost identical. Kai Havertz makes the same run and Marc Cucurella finds him. He's offside again but that looked much tighter.

It's another disallowed goal for Chelsea as Kai Havertz is offside as he runs in behind, rounds the keeper and slots it into the empty net.

Graham Potter was celebrating on the touchline but the flag went up immediately.

Good refereeing in the end but West Ham are getting hammered here!

West Ham have a rare venture into Chelsea's half as Declan Rice tackles Enzo Fernandez near the touchline.

Jarrod Bowen helps it down the line to Michail Antonio but he has his back to goal when it comes to him in the box and he's blocked off.

Chelsea have absolutely bossed it with possession in the first 15 minutes. Technically it is on the volley but he has just passed it into the net. Chelsea have been superb so far.

That goal comes as no surprise. West Ham have done absolutely nothing and it's been domination from Chelsea since the second minute.

On comes Tomas Soucek as Lucas Paqueta goes straight down the tunnel holding his shoulder.

Enzo Fernandez pounces on Lucas Paqueta and wins the ball just outside the West Ham box before firing it wide.

Paqueta is clearly in pain and immediately gestures he can't carry on. A big loss to West Ham.

Joao Felix spins away from Vladimir Coufal but can't link-up with Kai Havertz.

Chelsea retain possession and Noni Madueke holds it up well on the right. He's started strongly and looks to be holding his own.

Lucas Paqueta is back on but he's struggling with his shoulder.

Immediately, Joao Felix is in behind and he finishes it beautifully, chipping it over the keeper and poking the rebound in off the post.

It won't count though. He's offside.

Lucas Paqueta doesn't look comfortable and Tomas Soucek has been sent to warm-up. He might have to come off. The game gets back under way as he continues to receive treatment on the sidelines.

I was surprised to see Ruben Loftus-Cheek in the team, he must have been very good in training this week. Chelsea have bossed it so far, West Ham very much on the back foot.

Lucas Paqueta does well to bring the ball out after another attack from Chelsea, who are starting to dominate possession.

He's brought down by Noni Madueke and falls awkwardly, needing a bit of treatment.

Jude: With all these talents at his mercy, Potter decides to start Loftus-Cheek. Sideways passing and no end product.

Ruben Loftus-Cheek is played in behind by Joao Felix and he has Kai Havertz in the middle but Lucasz Fabianski gathers in the cut-back.

Reece James' free-kick is straight into the arms of Lucasz Fabianski.

West Ham get things under way and immediately Michail Antonio tries to link-up with Said Benrahma but his flick is read by Thiago Silva.

Mykhailo Mudryk then wins a free-kick at the other end.

Off we go in London.

Here come the teams and the bubbles!
