When you're a famous, successful person at 16 years old, the rules change for you. Everybody is doing things for you to make life easier so you can go out and play. And I think you miss out on lot of growing up and a lot of reality checks.

I think team sports probably teach you more about giving - about being unselfish and being flexible.

Tennis helped give me an identity and made me feel like somebody.

Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

Politics in Washington is a contact sport. But it shouldn't be a personal animosity sport.

There are games where the striker will be useful for the team in terms of creating space and being involved in the game, without necessarily scoring, but he'll have played an important role for the team. But, of course, over the course of a season, I have to score goals, as that's what statistics reflect.

Because I used to play a lot of sport, I've always been in decent enough shape. When I used to get asked to do a bit of body work before a photo shoot I'd lie and say, 'Yeah, I'm going to the gym.' I literally never did anything.

That attitude, that persona I carry is something I've always had with me. I mean, that's what made me successful, especially in football, and is making me successful now.
