I'm a competitor and a very proud man. If a guy beats me once, he'll have to do it again to make me believe him.

Although it was a great accomplishment to win a gold medal, as soon as they put it on you, that's it; your career is over.

We're all endowed with God-given talents. Mine happens to be hitting people in the head.

When I turned pro, Muhammad Ali was laying back, and I was able to fill up an area that was empty.

I think I've become one of the best finishers in boxing; if I hurt a guy, I normally take him out.

My ambition is not to be just a good fighter. I want to be great, something special.

Everything you want to know about a fighter is in his eyes. The look in his eyes tells the truth.
