I am just taking the top fights out there for me. People will get bored seeing me every day knock someone out.

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.

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.

People know I was the last true champion.

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

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.

I have always said I am a five-dimensional fighter.
