I have played with some great players during my time at United but I would have to put Paul Scholes down as the best.

I had an early taste of fame. I was 20, going out with TV presenter Dani Behr and we'd have paparazzi chasing us. I'm not comfortable being photographed, though I accept it is part of the job. I had to ask myself, 'What comes first, being a celebrity or footballer?

I've put myself forward to be involved. Whether I get picked, we'll have to wait and see. Obviously everybody is excited about it, about the Olympics coming to London and the football being played in different parts of Britain.

Nelson Mandela is my hero outside of football. I was fortunate enough to meet him a couple of times. He was really clued up on his football and he knew me, so that was just unbelievable. It really stuck with me.

If I feel I'm not influencing games, not scoring goals or making goals, then that's the time I'd pack it in.

As a footballer I can't imagine life without the use of one of my legs... Sadly this is exactly what happens to thousands of children every year when they accidentally step on a landmine.

I think after a big European game you're looking at four or five days. For two days afterwards I don't really do anything. I do a recovery the next day, which is bike work, a light stretch, some yoga and an ice bath after that. Then the second day I would just do the bike again for 20 minutes and then do some strides, which is box to box, just eight of them, just to get the legs going and the blood going again.
