European football games or evening games seem to take a lot more out of you because you don't sleep that night. And as you get older, it gets worse.

When you lose a game or don't play well you can't wait for the next one, because it soon disappears, the disappointment.

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

I like to let my football do the talking, I'm respectful of other good teams such as Arsenal.

I've always had people come up to me to say that they admire the way I play, and then they tell me they're not United fans. That's always been nice.

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.

There's never been completion in my football career because I've always been striving for that next thing. You listen to people who have finished and nothing replaces playing, but I'm still excited about not having to put my body through what I've put it through. And not feeling the disappointment that I feel.
