West Ham defender James Collins passes the ball straight to Arsenal forward Danny Welbeck, who plays in Theo Walcott. But Walcott, under some pressure from Collins, fires into the side of the net.

West Ham midfielder Cheikhou Kouyate has to go off to get some treatment after getting a knock but he's back on the pitch now.

Danny Welbeck should have put Arsenal ahead. Alexis Sanchez drops a free-kick into the box which Welbeck swings a boot at and barely makes any contact. Had he met it properly, it would have probably been the opening goal.

Michail Antonio, very ambitiously, tries to hit a first-time volley as the ball drops from the sky, but it's well wide. 

It's three shots each, but only Theo Walcott's effort is on target so far.

Moments after that penalty shout, Michail Antonio - on his return from injury - runs at the Gunners defence and is fouled by Hector Bellerin. Yellow card.

Arsenal want a penalty as Theo Walcott goes down under - mininimal - contract from Arthur Masuaku. Would have been harsh. 

An Arsenal chance as Hector Bellerin flies down the right and pulls it back to Theo Walcott but his 20-yard effort is at Darren Randolph.

West Ham captain Mark Noble disposseses Mohamed Elneny and charges towards goal but his effort from 20 yards out is wide of the far post.

And at the other end Alexis Sanchez tries to beat Darren Randolph from distance but it's well wide.

Granit Xhaka plays a ball over the Hammers defence but Alexis Sanchez can't quite stick his leg out enough to control the ball. It's not been the most exciting start to a game.

West Ham have a free-kick as Michail Antonio goes down 20 yards from goal. Manuel Lanzini steps up to take the free-kick but he curls it over the bar. The diving Emiliano Martinez might have had it covered anyway.

Arsenal forward Alexis Sanchez has the first shot of the game from distance but it's well wide.

Theo Walcott, captaining Arsenal tonight, goes on a run from halfway but he's chopped down by Cheikhou Kouyate, who won the ball, so no free-kick.

There are quite a few empty seats so far with some Arsenal fans staying in the concourse until the 13th minute (13 years since the Gunners last won the league) in an Arsene Wenger protest.

West Ham get us under way at the Emirates Stadium.

Petr Cech and David Ospina are both out injured for Arsenal so goalkeeper Emiliano Martinez makes his first Premier League appearance since 2014.

Laurent Koscielny misses out with an Achilles problem, with Gabriel taking his place. Mohamed Elneny replaces Francis Coquelin in midfield from the side who drew 2-2 with Manchester City on Sunday.

West Ham make three changes from the side who lost 2-1 to Hull.

Michail Antonio returns from a hamstring problem and replaces Sofiane Feghouli. Mark Noble takes the place of Robert Snodgrass, while Arthur Masuaku comes in for the injured Aaron Cresswell.

Diafra Sakho returns to the bench, having been out injured since November.

If ever there was a match where both managers were in the spotlight, then this is it.

While the footballing world waits for confirmation from Arsene Wenger on his future, Slaven Bilic has received a public vote of confidence from West Ham's owners on his.

Wenger has rightly alluded to the challenge he faces to maintain his record of always delivering a top-four finish for Arsenal.

The fact that they came from behind and didn't lose to Manchester City was important, but it remains to be seen if they have the mental strength in the remaining games.

They will hope to exploit West Ham's low confidence levels, as the Hammers look to avoid a fifth consecutive defeat.

Only three teams in the Premier League have picked up fewer points than Arsenal's four in the past six games.

Tonight they come up against one of them - West Ham (two points).
