It's punched away by the West Ham keeper but wait...

Arsenal win a corner right at the end of the half. Gabriel Martinelli wins it and will take it.

51.4% of the action has been in the West Ham United third over the last 15 minutes.

Three minutes added on as Eddie Nketiah glances a header well wide from Martin Odegaard's free-kick.

Vladimir Coufal slides in and takes the ball... and a lot of Gabriel Martinelli too. The West Ham defender is booked. He does not agree with the decision since he won the ball initially.

The passes completed count is 284-89. But West Ham have had the better chances.

Martin Odegaard shapes to shoot but plays it out left to Gabriel Martinelli. His low cross is cleared by Craig Dawson.

Eddie Nketiah shows great feet to almost get into the box but Thilo Kehrer stops him with a fine challenge.

West Ham striker Michail Antonio, only playing because Gianluca Scamacca is injured, runs onto a long ball, sends William Saliba the wrong way and blasts a shot wide.

Damian Fogarty: Saliba was hesitant to deal with the ball over the top to Bowen, then lunged in. Late back from the World Cup in more ways than one.

Mike Hall: Funny. West Ham player goes down after the slightest contact and gets a penalty, confirmed by VAR. Saka gets thrown around and doesn't get a penalty!

Mr C: I really don't understand why Saka's goal was disallowed.

Arsenal's Ben White steps past a defender but his cross is too high for Gabriel Martinelli to do anything with.

The Gunners were good until the goal but are definitely shaken.

Said Benrahma is one of three players to score a Boxing Day Premier League goal in both of the last two seasons, after Harry Kane and James Ward-Prowse.

Craig Dawson heads away Bukayo Saka's cross. Arsenal haven't done much since the goal. They need to rediscover that zip.

A lot of you don't agree with that penalty decision. I feel if Jarrod Bowen had thrown himself to the ground instead of trying to carry on people would be less angry?

Bindl: Football may as well be a non-contact sport.

Daniel: Big test now to see if we can bounce back. Been playing quite well until now.

Arsenal have conceded first for the first time in nine Premier League games, previously doing so in a 3-1 defeat by Manchester United in September.

Said Benrahma is West Ham's top Premier League scorer this season with three goals. Which probably explains why the Hammers are where they are.

West Ham up to 14th as things stand.

West Ham are very much bouyed by that goal. Jarrod Bowen races down the right and has a cross cleared.

A test for Arsenal and their title credentials here.

Michael Oliver has awarded six penalties in 13 English Premier League games this season, more than any other referee.
