Hello and welcome to our LIVE match coverage of West Ham United v Arsenal from Upton Park. Kick-off 15.00 GMT.

Lovely ball from Cresswell to Amalfitano but his cross is too close to the keeper. Kouyate tries to bend one but it’s easy for Szczesny.

Cazorla lines up the free kick and West Ham defenders are furious that the flag did not go up as Sanchez tries to get on the end of it.

Mazy run from Welbeck who goes to ground under a challenge from Song and wins the free kick.

Tomkins lofts in a free kick and Sanchez is then caught by O'Brien and Arsenal can regroup.

Now Sakho hauled down by Monreal, who has started shakily, to say the least.

POSSESSION: West Ham 50%-50% Arsenal

Cazorla almost plays in Sanchez but a great challenge from Reid before he can pull the trigger. Great start to this match.

All West Ham at the start of this match. Arsenal break and it’s great challenge from O'Brien to deny Oxlade-Chamberlain.

Amalfitano whips in a ball to Sakho who goes down under a challenge from Debuchy. There are cries for a penalty but nothing given.

It was a lovely strike as the ball came back to him on the volley following the corner but there was no celebration.

Probably the right decision. Looked like a pair of them were offside, Kouyate and Sakho.

GOAL DISALLOWED: Lots of early West Ham pressure and Downing wins his side a second corner in as many minutes. Song lashes the ball into the net but the flag is up for offside! Very dubious decision.

Given away by Coquelin but a heavy touch from Carroll and Arsenal win it back. A poor pass from Monreal results in a West Ham corner but Szczesny claims well.

Dangerous cross from Amalfitano well claimed by Szczesny. Arsenal sticking to their tried and tested 4-3-3.

Referee Neil Swarbrick blows the whistle to get us underway here at Upton Park. A win could see either side go fourth in the table.

FIVE MINUTES TO KICK-OFF: Arsenal have won away at West Ham more often than any other team in Premier League history (10).
