i think the fact they're adapting to roy keanes slowness is a factor.... i think they should let him go at the end of this season and bring in a new younger defensive midfielder. i know hes an outstanding player and his influence is incomparable, but they need every player to be at their best to compete with a team like chelsea.
I don't think he was a flop at Man Utd when ever he got a chance to play he usually scored there were just better players at Utd at the time so he didn't get the chance in alot of games. It shows he wasn't a flop by the Utd fans still chanting his name. I think he would be a good buy for a team in the Premiership that are in say mid table. I think the same thing will happen at Arsenal if he goes there there are to many better players there in that position so he will not get the chance apart from when people are injured or suspended.
