He wasn't pulling defenders with him because the rest of the Arsenal squad were clueless with their role in attack. It is easy defending against an individual. Walcott was the only Arsenal player actively using his brain yesterday. He recognised the high line you were playing and adjusted his game. Everyone else on the Arsenal team seemed to think it was some sort of possession game when it was more centred around breaking vertically and with speed.
Didnt agree with Sol on MotD about Walcott. Central, direct running does not equate with an "excellent game". He did make runs yes, but he wasn't pulling defenders with him and all of his runs started in front if the defence and not off the shoulder so he was easy to track.
Other than stare at the ceiling, I thought he was ok.
