Chelsea are dominant. They are finding all sorts of space in midfield. Mason Mount looks to capitalise but fires low at Lukasz Fabuianski, who saves.

The home side look ragged. A foul by Craig Dawson on Hakim Ziyech is necessary to stop Chelsea staging another attack.

Andreas Christensen has delusions of grandeur with a shot from way out. It heads high and wide, as you may expect.

Arjun: Just to remind everyone that we got Thiago Silva for free. Absolutely masterful.

Issa Diop now has to slide in to stop Kai Havertz getting a goalbound touch from a cross from the left. Chelsea threatening to blow the Hammers away.

Chelsea in the hunt for a second. A low cross from Reece James fires across the box before the Blues fashion a shot from a central position for Ruben Loftus-Cheek. A deflection takes the sting out of it and Lukasz Fabianski saves.

That's as good as the goal. Thiago Silva's the only one that's anticipated the shot, he's just shuffled back onto the line.

He's scored at one end and then he's done his day job at the other.

Brilliant at both ends!

Thiago Silva comes to the rescue on his own goal-line with a clearance to prevent Jarrod Bowen's low drive finding the net.

What a season the Brazilian is having.

Kai Havertz wins Chelsea another corner.

Good luck to Manuel Lanzini trying to challenge Ruben Loftus-Cheek for the ball. Like a Porsche trying to ram a tank off the road.

Chelsea fashion a chance for Kai Havertz. He rises well to meet Reece James' cross but heads straight at Lukasz Fabianski.

It's getting tasty, a really good battle. Declan Rice has left one on Jorginho there, much to Jorginho's dislike.

Jorginho is wound up here. He throws the ball away after thinking he's been fouled. The ref responds by booking the Italian and giving West Ham a free-kick.

From it, the Hammers create a low percentage chance for Michail Antonio, which he fires high and wide.

West Ham clear Hakim Ziyech's corner at the near post. Poor delivery.

That front-post corner, Craig Dawson should probably do better, it's a bit of a weak effort. You can see already that set-pieces are going to be huge here.

I'm enjoying this. Proper contest.

Chelsea now have a corner.

Chance!

Craig Dawson gets his head to the delivery with a header that deflects back to him. He snatches at the follow-up, though, and pokes it harmlessly to Edouard Mendy.

It is a test. Ruben Loftus-Cheek has to get in the mix to head Declan Rice's delivery behind for a corner.

Nice easy one for us to find the answer for that, Don.

West Ham have a free-kick near the Chelsea box. We all know how big a threat they are from set-pieces. A test for this Chelsea defence...
