All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

On your way to the top, you always get some chriticism. Criticism is a great motivation.

When you're successful for so many years, the scariest part is that you're getting too comfortable because you've had so much success.

I've been many times to Dubai and the U.A.E., and I have friends that live there. It would be exciting to stage world heavyweight championship fights in the Arab world. It's something Muhammad Ali achieved when he fought in Zaire or the Philippines. It's absolutely exciting to fight in countries where you have never fought.

I run, but boxing conditioning is different, so you have to get used to running in the ring. Boxing movements are very different. Swimming is one of the best because every single muscle is working. I swim a lot. I train very hard at things that mimic boxing. I have to do mostly sport-specific training, such as lots of sparring.

I would say that Roger Federer is pretty amazing. And Manny Pacquiao - he's such a tiny, little lightweight guy, but the way he fights makes people so excited.

I'm trying to keep the face of my opponent more or less not damaged but eventually to execute the plan and knock him out.
