You don't want to be going into any fight thinking you've got to get a knockout, or force a stoppage, because it takes you out of your gameplan.

I've had a Japanese judge, a Mexican judge in the past, and they have done some ridiculous scoring.

I've been through the highs and lows. I know what it's like to taste defeat and it's not nice.

I know what it's like to fight against the crowd from when I went to Denmark to fight Mikkel Kessler. He's like David Beckham over there, he gets blanket coverage in the papers all week, and you could hear a pin drop when I was landing my shots. There was no respect for The Cobra out there. There was no noise, no love, nothing.

I'm a winner.

My mum and dad split up when I was five years old, and that was quite upsetting. But ever since then, I've been very hard.

I'm quite a ruthless, cold-hearted bastard. I always have been.

Audley Harrison is quite a soft, gentle guy. He gives it all the talk but, when he's in the ring, you can see he's scared to death.

When I say I am going to win a world title, I mean it; when I say I'll fight the best, I mean it; I say I'll fight Joe Calzaghe because I wanted to. When he vacated, I lost sleep over that. It had nothing to do with money or the belt. He was renowned as the best super-middleweight in the world and that is what I want to be.

I don't talk for the sake of talking and I don't talk with a forked tongue.

You can't talk about Golovkin in the same breath as me. If he thinks he can beat me, he's not from planet Earth.

Gennady Golovkin is a small middleweight, I'm a big super-middleweight. The fight was maybe talked about a year after I retired and it was never going to happen.

I always give Calzaghe credit. He was a great fighter, really tough, unbeaten in 46 fights. He's never, ever given me any props at all. And for that I'd love to punch him in the face really hard.

There is an age limit of 35 on amateur boxing. They should consider putting an age limit on professional boxing.

I boxed till my late 30s, so 47, that's impossible really to be at your best and if you aren't at your best you shouldn't be boxing.

Boxing is not like any other sport, you have to weigh up the risk and reward. Things like playing football, tennis, you might be three sets to love down, but boxing you're going to the hospital on a stretcher and you know potentially you are going to get an injury you can't walk away from.

A three-month training camp writes you off, I wake up and I literally can't get out of bed.

It's not too late actually to speak to somebody about psychology, it's never too late.

Many top professional sportsmen from different sports see a psychologist.

I don't think I'll be fighting when I'm 40.

There have been many boxing comebacks over the years, and sadly many of them do not have a happy ending.

Some fighters had blinding speed and reflexes in their heyday but faded badly with age.

I've won titles at home, I've won them abroad, I've defended titles abroad and lost them, and gone on to dominate my next opponent to win them back.

My final fight was called 'Unfinished Business' - and I finished it.

The general public don't like boxers. They prefer tennis players.

I'm not in this for superstardom. I do it purely for the love of the sport. I just love fighting.

I don't feel any remorse or guilt after a fight. I can sympathise with an opponent who is getting a beating, but if it is the choice between him and me, it's not gonna be me.

I did it the hard way, I fought everyone I could and I would not have it any other way.

People can look at my style and my faults, point out all the things I didn't do as well as other fighters but I was never knocked out or stopped.

I absolutely love boxing. I live and breathe it.

I've been in the ring. I've fought in a title fight. I know what it is like to lose a fight. I know everything a fighter has been through.

I don't tell lies. I don't need to.

I wear my heart on my sleeve and tell you how it is.

Boxing is a hurt game if you can't be at your best, can't be 100 per cent mentally and physically switched on to performing, to win titles, defend titles, defend yourself in the correct fashion, then I don't think you should fight.

I've always been into sport, I watch all sport - I love golf, tennis, football and to me to box and have people in the arena cheering me on, I'll always miss that.

The only thing I miss is the actual fight night and the feeling of winning. I can say this with my hand on my heart, there is no greater feeling than standing victorious in the ring or in the case of my last fight, a stadium.

I've even fought with a broken hand, against Brian Magee.

When I won the title against Jean Pascal it also won me fight of the year.

It's questionable whether I believe in God or Jesus but I do believe in a spiritual world and some kind of afterlife.

I believe my grandma is watching over me and I draw strength from that.

I would have loved to have fought 15-rounders, because I always come on strong at the end.

As tired as I am, I can always go another round, and I feel the other guy can't.

While I can fight, I will fight. When I can't walk straight or my hands are knackered, then you've got to turn it in.

I'd love to box in Las Vegas - it's the fight capital in the world.

You are never going to top boxing at Wembley stadium.

I look back at the first Groves fight, and it was all so bad, so wrong. Everyone was telling me it was going to be easy, the bookies, everyone. Like an unprofessional fool, like an idiot, I listened to them. I didn't give myself the best possible chance.

There's weaknesses in every fighter.

You are either genetically tough or you're not.

I always like to get that finishing blow and satisfy the crowd.

The fans want to see a conclusive finish. It's quite a brutal, barbaric sport and the people who watch it want to see someone out. That's what I do for a living.
