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.

Sometimes success needs interruption to regain focus and shake off complacency.

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

I always ask myself why old heavyweights come back, but I plan to stay out of the ring.

I cannot fight everyone at once. I have to take one at a time.

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

I think Kirk Johnson is a more exciting fighter than Chris Byrd. A lot of people agree with me when it comes to that.
