I have got to feel I'm the best heavyweight in the world, ... If people don't consider me the best, I don't care. If everybody fights everybody, you'll know who the best guy is. Until then, it's everybody's opinion.

I used to be crazy about being the best, No. 1. I wanted to be considered No. 1 heavyweight in the world and everybody know it. But now, at this point in my career, how things have been going in my career and not getting certain fights and people ducking me, I just concentrate on who I am boxing and I do not worry about the unification thing. You cannot make somebody fight you. Whatever happens, happens.

Things are busy, ... When you get the title of world heavyweight champion, not only does WWE expect you to put the title on the line every night and perform at the top of your game, they expect you to be the flagship of the company, do interviews, be everywhere at once and spread the good word of the company. A lot of people don't understand that.

My goal is to be the undisputed Heavyweight Champion of the World.

There are 7 billion people in the world, but there's only one heavyweight champion of the world, and that's me.

I think it's great, ... I tell everybody that this is the best job in the world.
