Good evening and welcome to live coverage of Arsenal versus West Ham United from the Emirates Stadium. Teams to follow shortly.

That's full-time, Arsenal have won it 2-1.

Arsenal break right through the middle with Aubameyang. He lays the ball to Pepe whose shot is blocked, and Nketiah wins a corner after picking up the rebound.

West Ham have got everyone forwards here. Anderson tries to cut a ball back to Haller who is free on the penalty spot, but Ceballos gets in bravely and is fouled as he intercepts the ball.

We will have a minimum of four additional minutes.

Anderson replaces Masuaku for West Ham.

Two changes, one for either side. Haller is on for Fornals, while David Luiz replaces Saka.

Arsenal have cut West Ham open again. Saka dances in from the left and prods a pass to beat the offside trap and release Ceballos into the area. Ceballos draws out Fabianski and then squares it to Nketiah, who taps into an empty net from seven yards out.

Masuaku clips in another dangerous cross which Leno flaps dangerously out to the right. Fredericks puts it straight back in, but Soucek can't get above Holding to connect with the ball.

Yarmolenko replaces Bowen for West Ham.

Xhaka finds Kolasinac with a superb pass. He's in acres of space on the left of the area, but can only slash his cross straight out for a goal kick.

Arsenal are back on the front foot here, but a succession of poor crosses and corners don't get past the first defender.

Nketiah replaces Lacazette for Arsenal.

Saka tries to jink through two challenges and into the area on the left. He looks to have made it through but Fredericks just about gets back to bump Saka off the ball and win it back for West Ham.

Saka springs the offside trap on the left but Diop gets an excellent block on the cross to put the ball behind for a corner.

Bowen cuts in from the left and his shot from the edge of the area is blocked by Gabriel. Soucek shoots from the rebound but drags it horribly wide.

Antonio holds the ball up well for West Ham and wins a throw-in deep in the Arsenal half. West Ham have had the better of the second half, can they push on and earn a surprise victory?

OFF THE BAR! What an almighty scramble! Masuaku loops a cross to the back post, where Antonio heads the ball onto the bar. Leno rushes out to gather the rebound, but spills it and Bowen can't guide his shot past the goalkeeper as Arsenal hack it clear.

A pause here, as Xhaka and Soucek have clashed heads. Both look ok to continue.

West Ham win it deep in their own half, and work it to Antonio on the right. He cuts in to he centre and shoots from 25 yards but Gabriel gets in the way of the shot.

Pepe replaces Willian for Arsenal.
