Real champions fight through adversity.

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 feel it when I need to train and I do what I feel like I need to do. I don't get obsessed with one style or one skill.

I don't care about anything I don't need to care about.

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

When I'm in there I'm just in my zone. What people think about when they're looking at me, that's their business. If there is a bit of that, I am fine with it, each to his own.

I don't give a f***. We're not fighting. I don't care what anyone thinks about me. All the stuff I have to do outside the fighting, the promotion, this, I don't give a f***. But when I am facing up for a fight, I know what they're thinking. I can read their minds. When I am going face to face with an opponent, nose to nose, I can smell the fear, and I'm feeling no fear at all.
