Patience is a part of boxing. After I had missed out on the Olympic gold medal in 1984, a lot of people tried to talk me into turning professional quickly to make money. They told me that the next Olympics in Seoul would be boycotted again, that I was wasting my life, blah blah. But I still had unfinished business. I wanted the gold medal, and I got it in ‘88. Only then was I ready to turn professional.

For me, there's never any bad blood - unless you do something to me.

The Tyson fight was like the hardest I ever trained for a fight in my entire career.

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

Fighters used to be afraid of the Russians, Cubans but then I'd figure them out and figure out how to beat them.

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

I was very aggressive as a child. At primary school in London my attitude was 'If you don't do what I say, I'll knowk you out', and I was eventually expelled for fighting.
