Politics is comparable to boxing. The only thing is that in politics there are basically no rules. In boxing, you can get a black eye, but in politics you can get poison in your food or a bullet in the head. It's definitely rougher and tougher than other sports.

All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

[Anthony Joshua] is the best man in the division and I believe this excitement speaks for itself. This is what the fans want and this fight must happen.

Sometimes it's boring because it takes time, but it's enjoyable. So beating up people for a living is really fun.

From nothing to everything is a long way, from everything to nothing is one stop.

In Soviet times the border was closed so we couldn't get out of the country, and I had been reading Robinson Crusoe. I wanted to see the ocean, I wanted to see boats, I wanted to see black people, because we didn't have that in the Soviet Union. I was all excited by that stuff.

All of my fights are planned. I study my opponents from A to Z. How he walks, how he looks, how he speaks, gestures of the human body, which is a certain language that provides you lots of information if you have the ability to read it.
