Mayweather was my first professional defeat and I took it really, really hard.

My game was all about strength and mauling opponents.

When I stepped up a division I can remember suffering the worst fatigue I had ever felt. I noticed it massively.

I can remember crying in the Kippax at Maine Road when City were relegated to the old First Division in 1996. Dropping out of the Premier League seemed like the worst thing imaginable - and what didn't help was the fact United were winning just about everything going at the same time.

Jose Mourinho is the Floyd Mayweather Jr of football management. You either love him or hate him.

Kostya Tszyu was the best payday of my career to that point, even though I thought it should have been better.

Boxers don't tend to come from Cambridge or Oxford. Sometimes the things we say don't come out well. We are not known for our vocabulary.

I've been asked by 'Big Brother,' 'I'm a Celebrity - Get Me Out of Here!,' 'Strictly' and 'Dancing on Ice,' but it's not for me.

I'm very fortunate. I've looked after my money and I'm happy with where my career is at as a trainer and a promoter.

I've never been a red carpet hugger unless it is for charity.

Just like footballers want to play at Wembley, the Nou Camp and the Bernabeu, boxers have their dream arenas too.

Everyone wants to be a world champion, but when you take that first punch it will tell you if you really want to be in this sport or not. For me, there was no doubt.

You know if you want to be a boxer the first time you get hit on the nose.

I'm not going to say I was Britain's greatest ever world champion. I think Joe Calzaghe was the best - although I think I fought a lot better fighters.

For all the success, I never acted any differently. I've always done the same things and I can honestly say I've not changed in the slightest. Sometimes that's the problem.

You write an autobiography because you want to tell people how you felt about a certain matter at that time.

My fallout with my family was heart-breaking.

Having been a world champion, I would love to go on and train a world champion too.

Fame has never been high on my agenda.

I always laugh at people who strive to be famous because all you do is get mithered to death by everyone.

Muhammad Ali was the one who started it, winding up his opponents, but he always did it with a twinkle in his eye and a bit of class about him. Mayweather is just insulting from start to finish.

Winning the world title was my goal as a kid, but being the pound-for-pound champion would be the ultimate.

Right from the beginning I wanted to test myself against the best, against real champions.

My second pro fight was at Madison Square Garden, on the undercard of Naseem Hamed's fight against Kevin Kelley.

It's unusual for me to be in front of an audience without somebody trying to knock my teeth out.

I don't want to go on forever and leaving the sport is the hardest decision.

Because of my style, I always make hard work of my contests.

I want to be recognised as a great fighter; and not just in England.

There's no better feeling in the world than when I walk in a pub, or a nightclub or a bar or a supermarket, anywhere, and you see people out the corner of your eye and they're going, 'Hey, there's Ricky Hatton. Isn't he a good lad, coming for a pint with us in here?' It makes you feel proud.

Ultimately when I fell out with my parents, I hit rock bottom. I didn't care whether I lived or died to be honest with you.

I was getting depressed, I was going out, having a few drinks and the worst thing you can do with depression is add alcohol to it.

I've fought at such a high level I couldn't have people look at me and say, 'well, he's just fought someone to knock them over.'

Depression is a serious thing and, after my defeat to Pacquiao, I was facing retirement and didn't cope with it very well.

I don't mind getting beaten by Manny Pacquiao, Floyd Mayweather Jr and people like that, but I'd hate to go into a training camp with my heart not fully in it and risk getting beaten by somebody who shouldn't be beating me.

I've always been the local lad, boy done well, kid next door.

I was fortunate enough to fight at Madison Square Garden, Vegas and the City of Manchester Stadium.

I was always very depressed, even when I was a youngster.

The manner of my defeat against Mayweather and certainly Manny Pacquiao was a bitter pill to swallow.

It makes me very, very happy to get someone a world title shot, which I've done with a few fighters, or a European title shot or a British title, and I see them lift that belt above their waist and they come to me and say 'Thanks Ricky. I've just paid my mortgage off with that.' That's what its all about.

My mum and dad had four pubs when we were growing up, but the main one was the New Inn in Hattersley, on the estate. It was a very good pub.

I always loved training to get fit, make all those sacrifices that you do, but it just wasn't there after Pacquiao.

It doesn't matter how many people say 'don't be hard on yourself,' I feel like I have to redeem myself to my fans, my family and the whole of British sport.

I never manufactured my persona.

They say 'you've over trained, you've left it in the gym' is the most common phrase used in boxing but my god it is the truest.

If, and when, I do eventually decide to retire, the announcement will be made by myself. I feel that I have earned the right to do it myself.

I wouldn't say Floyd Mayweather Jr is running scared of Amir Khan. Floyd doesn't need to run from anybody. Look at the names he has beaten during his career and it is an impressive list.

Sir Alex Ferguson sent me a letter wishing me good luck before my fight with Floyd Mayweather Jr. He also sent me a United shirt, signed by all of the players. It was a really nice touch and typical of the man who has always made himself available to managers in this country whenever they've needed advice.

He's a very, very clever fighter, Manny, but you'd have to say the cleverest fighter in boxing is Mayweather. He adapts his style against whatever opponent he faces.

I want to go down as a champion who redeemed himself, made up for letting everyone down and regained his self-respect.

Would I change anything? I don't know, that's a double edge sword for me.
