Theo Walcott scored a brace for Arsenal as the London derby went the way of the Gunners, despite the efforts of West Ham.
Walcott has spent most of the season so far on the sidelines with a stomach injury but played the full 90 minutes again against West Ham, scoring his first headed goal.
The Gunners won the match with ease, with a brace coming from Walcott. Arsenal beat West Ham 3-1. A goal also came for Lukas Podolski on his comeback from injury.
Both are going to be needed if Arsenal are going to push for the title this season, and they could well be the factor which wins it for them.
