The transfer window

One of the most damaging things of all when you look at the relationship between Wenger and the Arsenal fans.

This summer was just the latest in a long line of failures and broken promises from Wenger, but passing up the chance to bring Cesc Fabregas back to the club really tipped the fans over the edge.

Add to that years of buying players that were below par, not needed or generally nowhere near the standards of their rivals, and you can see why the Arsenal faithful are more than a little bit annoyed.
