To do anything to a high level it has to be total obsession.

I don't use machines - animals don't use machines.

You can take on the world in a good suit.

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.

It's gone, boxing's gone. What is there in boxing? Who is there to talk about, who is there that people go, "Yeah I want to fight him?", and fans go "I wanna see that fight"? There's Floyd Mayweather, and he is 38, 39, he's maybe got one fight left. What else is there? He'll have a last fight or two and a couple of guys will get a few million dollars, but way less than I'm gonna be getting in future. This sport is getting bigger all the time, and I am making it bigger.

Getting enough protein is important when I train, to help build muscle and recover, so I'll supplement with protein shakes.

It is the most powerful submission in the sport. It is a beautiful thing. You're holding them into you, their back is on you, and you are basically choking them gradually like a boa constrictor and once you've got them, the pressure goes on and they have to submit or they are going to stop breathing. It happened to me early in my career, and I panicked, and gave in, I tapped out too early. I learned a lot from that. I learned from it, learned how to do the move better, learned how to avoid it being done to me.
