It's almost 2-0 to Arsenal now as Theo Walcott slips in Danny Welbeck, with Hammers keeper Darren Randolph doing well to keep his effort out.

West Ham heads appear to have dropped. Is this going to be a fifth consecutive Premier League defeat?

As things stand, Arsenal are six points behind the Champions League places - thanks to Manchester City trailing at Chelsea. It could be down to four (with a game in hand) if the Gunners can score.

Both Jose Fonte and Arthur Masuaku are OK to continue, thankfully for the Hammers.

Fonte's first act since coming back on is to commit a foul.

West Ham have two defenders down injured - as Jose Fonte and Arthur Masuaku clashed heads while trying to deal with a corner. They are both getting treatment.

Alexis Sanchez finds Mesut Ozil in space in the box and it's a sensational goal-saving tackle by James Collins. A genuinely world-class bit of defending.

Mesut Ozil is in on goal, but it's too good to be true. He was offside after James Collins stepped up.

Arsenal get the second half under way.

West Ham midfielder Michail Antonio only lasts 45 minutes on his return from a hamstring injury. He only made 10 passes in the first half, fewer than anyone else for the Hammers. Robert Snodgrass replaces him.

Arsenal keeper Emiliano Martinez hasn't had to make any saves in his first Premier League game since 2014. He's had 13 touches though, two more than Danny Welbeck.

Here are the match stats from the first half at the Emirates.

It's half-time in the other three 19:45 BST kick-offs too.

Swansea are 1-0 up against Tottenham, Hull are beating Middlesbrough 3-2 and Southampton and Crystal Palace are 1-1.

In the 20:00 BST games, Chelsea lead Manchester City 2-1, with Bournemouth 1-0 up at Liverpool.

Arsenal ended the half well on top, but without being able to score. It's not been a classic.

Mesut Ozil hits the post, but he was offside anyway.

Theo Walcott is almost in for Arsenal but Darren Randolph flies off his line to smother his effort.

Arsenal have their best chances of the game so far - Hector Bellerin has a shot blocked by Jose Fonte, with Mohamed Elneny's follow-up effort deflected over by James Collins.

And Danny Welbeck heads at Darren Randolph from the corner.

West Ham midfielder Manuel Lanzini goes into the book for fouling Hector Bellerin. The referee let play go on, before showing the Argentine a yellow card after the Gunners attack ended.

Ball falls to Arsenal midfielder Mohamed Elneny outside the box and he shoots - I mean I think it was a shot - with the outside of his foot. It goes halfway between the goal and the corner flag. Shocking.

I'd love for you to stay here with me obviously, but if you like goals - you're in the wrong place.

There have been between one and four goals in each of the other five Premier League games tonight.
