Could James Ward-Prowse be an inspired signing for £30 million? I wasn't sure - but he is already proving his worth. Two fantastic deliveries!!

Chelsea are threatening whenever they get the ball down the left.
Jackson is making some good runs up front.

There's no way Mauricio Pochettino knows his best XI is there? I bet he can barely remember who is at the club and who isn't.

Chelsea 1-0 down already. They might need to dip their toe in the transfer market.

Chelsea captain Ben Chilwell swings in a cross from the left and Nicolas Jackson heads over from 10 yards. He was under the ball sadly.

Raheem Sterling and Nicolas Jackson play a one-two and goalscorer Nayef Aguerd pulls back Sterling to get the game's first yellow.

End to end. In so much as West Ham play a long ball and then Chelsea play a long ball.

So, so sloppy from Chelsea so far.

It was coming. Second corner poorly defended by Chelsea and the Hammer's take the lead... Shocking defending there.

This is very close. Get those lines out....
The lines are red. Nicolas Jackson is just offside so it's no penalty. Inches in it.

Chelsea had a warning five minutes ago. A carbon copy of the last corner.
West Ham know the quality James Ward-Prowse brings. Two corners, one assist already.
West Ham 1-0 Chelsea
Penalty to Chelsea? No, it's offside.
Nicolas Jackson runs through on goal and goes round Alphonse Areola, who takes him out.
The flag goes up then.
Actually they're checking this. If he's onside that's a penalty.

His [James Ward-Prowse] set-piece delivery is on point and that just proves it.
For Chelsea it is a miss match at the back post for Conor Gallagher against Nayef Aguerd.
West Ham 1-0 Chelsea
It was Conor Gallagher who was nearest Nayef Aguerd but couldn't stop him.
Nayef Aguerd
James Ward-Prowse's second West Ham corner produces a goal.
He finds Nayef Aguerd at the back post and the West Ham defender is totally unmarked to power a header past Rob Sanchez.

It's a pretty fluid system for Chelsea at the back. They change between a back three and a back four depending on when they have possession of the ball. Levi Colwill is the one who alternates between a left-back and a centre-back.
