I don't know if I will ever be satisfied but I will keep going until hopefully I am.

When I won the world title, I am not going to lie, it was an unbelievable feeling. It was like a weight off my shoulders, a goal I'd set myself for so long and one others had talked about. When I got there I realised how I am never satisfied and how I always want more.

If I am still fighting at 35 I will be disappointed.

I had a slow couple of years and people forgot about me.

This sport is so tough and fighters start out with the same goal but very, very few get to achieve it.

Defeat is tough.

I lost in the amateurs, losing a controversial fight that stopped me going to an Olympic Games - and it's not a nice feeling.

I've been there for every world title fight my family have been involved in. I've been there in the changing rooms. I've experienced the nerves - perhaps more when it's not me and when it's one of them.

Any fight I feel pressure, just the same as the last one, the next one will be just as important.

Badou Jack is a puncher, but so am I.

We do need maybe younger or more experienced judges but where you can get them I don't know. It's like in football, who would want to be a football referee? You'd just get criticism all the time.

There's no praise for scoring a fight right, just criticism for one you get wrong.

Even with ex-fighters as judges, it doesn't mean they can score a fight, you'd still end up with debate and opinion.

I have my own goals, standards and have my own pressure.

I'm very thankful people have paid their hard-earned money to come out and watch me.

I want the best names in the division. The fear brings out the best performance in myself.

I'm a perfectionist and I always want to do the best as possible.

Listen, I know how good I am, how good I can be.

I was obsessed with the Turtles, the Teenage Mutant Ninja Turtles. There's Leonardo, Donatello, Michelangelo, Raphael and my dad used to call me Callemundo, saying you're the fifth turtle.

As long as it was George Groves in the opposite corner with his world title, the date was irrelevant to me. I was prepared to wait as long as it took to get that fight for the world title.

I would like to unify and test myself against other champions.

I want to bring a world title back to Liverpool and I would love to defend my world title in my own city.

He's one of the best assistants and one of the best evaluators of talent that I've ever been around, ... I think in the next week or two we are going to try to name him associate head coach because he's been that good.

He's the best natural scorer of all the big kids. He's not the biggest by any stretch, but at any time he can take up space, he can move people without pushing, just by using his body, and you can't move him. He's a very difficult kid to move, especially with his hard work and passion for the game.
