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.

Different fights bring out different things. I consider myself a seasoned professional. I have done things in the gym that have not come out yet. People would be amazed if they saw me train.

As a boxer I took the liberty of using not only my fists, but also my head.

There were different heroes with different images. There was Mike Tyson, the animal, there was Evander Holyfield, the devout, the priest. And there was me, the thinker, the intellectual boxer. So there was something for every fan, if you like. The public could always identify with one of us.

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

I wanted to prove I was the best fighter in the world.

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