Boxing is an addiction.
In 2017, I boxed in front of a home crowd in Sheffield and became the WBA super-middleweight world champion. After four attempts I had finally fulfilled my childhood dream, and the experience was as great as I had always imagined it would be. It was without doubt the best moment of my career.
I've never been the biggest boxing fan. If I know the guy I will watch him. But if it's two great fighters and I don't know either of them then I won't bother.
Fighting in a heavier weight class is a big achievement on its own.
I always thought I would be a boxing champion.
At the end of the day, that's just boxing - it's a different sport altogether. But when I finish fighting for the UFC, there are so many different options I have. Boxing is another option I could take.
My main goal is Vitali Klitschko. I figure eight rounds, I nail him with a right hand, a left-right combination and it's a wrap.
It's boxing. It's about getting people interested. If I didn't say some stupid things from time to time, there wouldn't be that many people interested in me. But I let my fists do the talking when the bell rings.
I've always boxed, I always taught boxing.
One of my short films was about a boxer.
When I win, I send shock waves through the boxing world.
I first got into boxing when I was quite young. I was about 12 when I won my first boxing match.
I'm the best heavyweight outside the world champions, and let's not forget that.
I'm always down to fight a legend of the sport.
Boxing was the only career where I wouldn't have to start out at the bottom. I had a good resume.
If I hit the Klitschkos with the same shots I was hitting John Ruiz, both of them would go over.
I wanted to fight guys like Shane Moseley, Miguel Cotto, and Alvarez.
When I was younger, growing up in Pittsburgh, they had a 'Golden Gloves' program through the Boys and Girls Club. In Pittsburgh, New York, Philly, Washington, those areas, I would go and spar at competitions.
I always said the 155-pound belt's been in so many grubby hands, man.
I was fighting at 125 pounds when I was 15 years old... then became a champion at 126 pounds at 25 years old.
Different days, I think about different victories. Ricky Hatton is one of those fights. I respect Ricky Hatton. He's a warrior. He's a hell of a warrior.
If I don't knock out Lennox Lewis, I am going to beat the hell out of him.
Oh, sure, I love boxing.
I'll fight Wladimir Klitschko and knock him out if he comes back; I'll definitely knock him out.
I would love to fight Ricky Hatton.
