Pain is part of the sport.

I believe in believing. My coach John Kavanagh is a big atheist and he is always trying to persuade people to his way of thinking, and I think what a waste of energy. If people want to believe in this god, or that god, that's fine by me, believe away. But I think we can be our own gods. I believe in myself.

To do anything to a high level it has to be total obsession. Ask José Mourinho, he wouldn't know a thing about me, my sport - he knows football, and to get to high levels you have to be insane, nothing else means anything. I respect all forms of movement and lifestyles, but I am in a bubble. I wake up, it is in my head; I go to sleep, it's in my head, 24/7.

Boxing is going to have to catch up with the kind of things UFC is doing. They're getting left behind.

I mean I love movement. I mean the energy that comes from the way I move. We get energy from how we move. I mean the control I get from knowing everything about how my body feels and how it is working.

I will cross that bridge when it comes. I am not stupid. I am a very bright guy. I know that in the fighting game, you get people who get brain damage and do themselves long-term harm. I am into it in a big way, and I am good at it, and I am going to get very, very rich and then I will get out and we will see what comes after that.

As far as I'm concerned, I just speak the truth.
