It's a very interesting fight [Klitchko vs Tyson Fury] because this is the first time [Wladimir] Klitschko is fighting someone as big as him and with longer arms. He will have to be a little bit more aggressive, otherwise the younger guy will have more speed and more energy and I think that may be the difference.

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

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.

After about 25 fights you don't always have to keep going to the bathroom before the fight.

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.

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

Whatever I do, I always want to get better.
