LA Galaxy star David Beckham admits he would've surprised Roy Keane with the some of things he did away from the game while they were together at Manchester United.

He said: "Maybe there are a few things I've done in the past that I shouldn't have done, but you learn.

"I've been criticised by Pelé and George Best in the past - people I really respect.

"Roy Keane probably couldn't understand some of the things I was doing outside the game. But if you ask him if I was professional once I was training or playing, I know what his answer would be."
