Why Roy is Keane to go on and on

MANCHESTER UNITED skipper Roy Keane wants to silence his doubters by playing on for three more years at Old Trafford.

Fears have been raised over the 31-year-old midfielder's ability to continue to compete at the highest level as he battles to regain his best form following hip and knee surgery last season. But, as with so many other critical points in his career, Keane is determined the critics will be proved wrong.

"People are saying I'm not the player I was and I'm finished with football," Keane said. "I've been a professional for 13 years and had a lot of pats on the back but this is the worst criticism I have had in my career. You have to try not to get too carried away with the success and try not to get too down with all the negative stuff.
