Fletcher didn't play in the final last season. He was a unused sub.
Also, Nasri is a very good player and today he actually was the most determined player, Van Persie on his day is also very good. Arsenal do play attractive football, but they fucked up by selling Hleb and Flamini.
Also this is why I think Walcott isn't that good, he may develop into a good player but his game is so one dimensional, he has awesome pace thats about it and stick close to him and he will do fuck all.
