The result means that West Ham miss an opportunity to draw level on points with Chelsea in fourth - instead, they're left two points behind after their game in hand. Arsenal, meanwhile, climb to ninth.
Arsenal pull off a fantastic comeback to draw 3-3 against West Ham. The hosts made an electric start: Lingard got them going with a brilliant strike, before Bowen and Soucek added to the scoreline to give them a seemingly impregnable lead. However, Arsenal rallied superbly.
Lacazette had a strike deflect off Soucek and in just before half time to give them hope, and this only grew when Dawson turned Chambers' cross into his own net on 61 minutes. Antonio missed a chance to seal the game when he hit the post late on, and it opened the door for Lacazette to head in Pepe's cross with 10 minutes to go, to rescue a point for the visitors.
