Arsenal missed the chance to go back to the top of the Premier League table on Thursday night. The Gunners remain second and two points behind title rivals Liverpool after slumping to a shock first home defeat of the season in any competition in a festive London derby at the Emirates Stadium.
Tomas Soucek controversially gave in-form West Ham a 13th-minute lead on the night, with the goal allowed to stand despite question marks over whether the ball had gone out of play before being hooked back into the box by Jarrod Bowen. There was no doubt about the second goal after half-time though, with former Arsenal defender Konstantinos Mavropanos heading in a trademark James Ward-Prowse set-piece delivery off both the crossbar and post.
Arsenal will hope to bounce back quickly with another derby at Fulham on New Year's Eve, while the Hammers move into the top six before hosting Brighton next.
