Was The Loss Wenger’s Fault (Again)?

Manchester United managed to defeat Arsenal once again and even though the Gunners were on a very good run in the game, Wenger decided to switch things around. Do you think that maybe this time it was only his fault that the game turned out this way?

First of all, why would you change Chamberlain who had an amazing match again, and put in Arshavin who showed us how much of a bad form he’s in last time he was on the pitch? And second of all, when will the manager understand that Ramsey lost a lot when he was injured and never quite retrieved to his old amazing form, managing only to put in average appearances?
