I used to imagine it. I used to pretend that my Peugeot driving to the gym in the rain in Dublin was a Ferrari on the Vegas strip. And now that I have that? I can't even describe that feeling. That's why I like the best - the best cars, the best food, the best watches.

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

The surface below your feet is so special. It is not like a boxing ring, not like a wrestling mat, it's its own thing, and when I am there, I am floating, I am moving with total freedom, I am free. And when you know, when you just know you are going to win, like I do, there is no better feeling.

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

I think I am the greatest fighter in any class.

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.

Whoever said it's tough at the top is talking absolute sh*t.
