I don't think Arsenal are neccesarily lucky this season. Wenger has just given them immense belief.
I think alot of people underestimate Wenger as a manager. I'm not saying he's up there with Fergie in terms of ability but in terms of importance to the team he is. Some of us thought that Man Utds team was poor but Fergie was getting the best out of them, its so far turning out to be right, managers like that are in a league of their own. Moyes has come in and has lost 3 of his first 6.
I think it's the same at Arsenal, not the GREATEST team but they have talented footballers who can all play football well, little intricate passes, can play well in tight areas of the pitch etc. and Arsene has done a great job with them, you get rid of him and bring someone else in and i feel they wouldnt be as good as they are.
