Recently I donated money to the establishment of the Muhammad Ali Foundation in Louisville. I regard that as a kind of payback. He smoothed the way for us. He wasn’t just a great person who had conviction, but made the sport of boxing great. He was the first superstar, he made our stock rise. Without him we wouldn’t have earned so much. Americans from every walk of life have contributed to the foundation: Bill Clinton, Angelina Jolie, Brad Pitt. Unfortunately I was the only American athlete to make a donation. There’s not enough respect in our business.

How can you trust a man who can talk for 5 minutes and you cant understand a sentence of it!

I'm undisputed and there's no disputing that.

A great champion needs a background in amateur boxing, I’'m convinced of that. There you learn everything that you’ll need later as a pro. Someone who’s got more than 400 amateur fights behind him no longer gets nervous before going into the ring and doesn’t lose his nerve during a fight. You know all the boxing styles, you’re prepared for anything, you’ve got the pedigree that you need to be a successful pro.

It's not rage that drives me, it's competition.

People know I was the last true champion.

The mission I set out on in the beginning - to become heavyweight champion of the world, undisputed, lineal champion - you could say that mission is complete.
