I agree he is no angel, but I think he is probably ok 99% of the time and its just alcohol fuelled aggression issues.
He has been lots quieter recently, he is from a really rough family and area, loads of money and no guidance.
If he is sober you never hear of any bother with him. He has demons thats for sure and he seems to be addressing them in the last year or so.
When you hear him in interviews he seems a nice guy and actually comes across quite intelligent.
Weather or not that makes him a c**t thats up to you, in my opinion he has taken quite large steps to addressing his personal issues and deserves some credit for that.
Dont get me wrong though I'd never defend what he has done to others but as a NUFC fan I support him with his treatment and wish him the best for the future.
