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.

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.

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.

People want to see me back in the ring. I think it is more of a drag lying around on the beach.

The danger of a closed mind is that it can also leave good things like love, compassion and reason on its outside.

Boxing and chess are similar. It’s about the choice of means. Sometimes I need a pawn, a bishop or a knight to defeat my opponent. It’s about finding the best way. A good boxer has to be variable. He doesn’t just need to know how to punch. He must also know how to protect himself, how to defend, how to avoid the opponent’s punches. Only a complete fighter can become champion.

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