He may have been at Carrington or not but I feel most people have not actually seen Roy Keane play before his injury. Roy Keane at one time was the best midfield player in the world.
There was nothing he could not do. He was fairly quick, he can dribble, he can tackle very well, he can pass very well, he read the game very well, he can shoot, he can score goals, we can head the ball very well and he also can kick the hell out of the opposition as we all know. He led by example. I don't think we would have beaten Arsenal at Highbury if Roy had not taken on Viera before the match.
It's obvious he is bitter about how he was kicked out but he still loves United. It was brilliant to hear him say in his usual dry way that not many clubs have won the PL three times in a row, referring to city's struggles to do so.
