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.

If people want to believe in this god, or that god, that's fine by me, believe away.

I won't ever shy away from a fight and if it makes sense down the road, I'll do it. But it will be on my terms.

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.

I love money, and I love movement. I like what it has let me do for my family. I have paid off my mum and dad's mortgage, I've bought them two BMWs, they can have anything they want. I am buying a fleet of cars for myself. I have unemployed my sisters, they don't need to work, don't need to worry about a thing.

I try to eat healthy all the time. I don't eat takeaways. I drink mostly water or coconut water.

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.
