I agree. Ever since he took over I always enjoyed watching Arsenal play. Some of the football at its peak was breathtaking. Did he stay too long in the end, quite possibly, but some Arsenal fans should be careful what they wish for. Look at what happened to Utd after Ferguson retired and even now they are finally having a bit of success it's hardly the entertainment and free flowing football they were used to for two decades.
I saw Arsenal take my team apart in an FA Cup match (the invincible team) and to this day it's still the best game of football I've ever seen live. There was no way you couldn't applaud the football they were playing. Sensational stuff. We got stuffed and yet I'd never enjoyed a game more. Henry got a standing ovation from the entire crowd when he was substituted. Never before or since have I witnessed that for an opponent. That to me is what football is about at its best. Those days when you come away from the ground and think, that's why I go to football.
Yes, Arsenal have not been great for a few years now, but now and again that magical interplay shows up for a goal or two and brings back those memories of their glory times when it was weekly occurrence. Give me that any day of the week than the turgid bore fest that Mourinho offers up.
While SAF is the most succesfull manager, Wenger was the most influential one. He really changed English football.
At times Arsenal played breathtakingly beautiful football, even when they were less successfull (remember that Wilshere goals against Norwich, best goal i ever saw).
