Ali's belief in himself was something I picked up on, and it's become my own philosophy.

You get these moments in the ring that live forever. That's what Muhammad Ali accomplished, and I hope that I have, too.

Boxing is the ultimate challenge. There's nothing that can compare to testing yourself the way you do every time you step in the ring. On the downside, you meet a lot of really bad people in boxing, at all stages of your career.

Boxing was the only career where I wouldn't have to start out at the bottom. I had a good resume.

Every time a young player comes in, he is excited and wants to prove himself, but also in football, the other players want to prove themselves to any new player that comes in, so that competition is the only way to stimulate performance.

The whole London football scene is now financially more powerful and ambitious than ever before. That reflects the city's economic might and its multiculturalism. Now West Ham have a new , and Spurs and Chelsea will follow. And the London clubs have widened their areas of support.

Here's my take: People watch sports to get away from day-to-day stresses, work, illness, financial worries. We don't need to be reminded of political divisions.

I'm more mature, my game is more mature, and I can do a bunch of things on and off the court to fully maximize this team's potential.
