There's never been completion in my football career because I've always been striving for that next thing.

In my career, there've been three stages really. There's been the stage when you come into a team, you don't feel the nerves, you just go out and play. Then through your 20s you start thinking a lot more about the games and what's at stake. And then, as you get more experienced towards the end of your career, you enjoy it a lot more and you're a lot more relaxed.

I have always considered myself to be very fortunate. To play for the biggest club in the world, which also happens to be the team I supported as a boy, means I have never had to consider changing away from Manchester United.

I had my footballing heroes such as Bryan Robson and Diego Maradona but my dad was a rugby league star, and he was my real hero. But the relationship with my mum was rocky and we saw things that would affect any youngster.

Celebrity culture, it's everywhere, isn't it? It's reality TV, Big Brother. I didn't become a footballer to be famous, I became a footballer to be successful. I didn't want to be famous. Now people want to be famous. Why? Why would you want people following you about all day?

My dad played rugby, so I used to watch a lot of rugby union and rugby league.

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.
