Ali could only fight a couple of ways. I can fight five or six different ways.

I may be born in the U.K., but nobody takes away from the fact that I'm an Arab, and I'm proud to be Arab.

I am not into guys who powder-puff punch and run round the ring for 12 rounds. I'm into guys that want to shock the world with devastating power.

You're either good at boxing, or you're not.

I love it when fighters are textbook.

I could have brought Kevin Kelley to my own backyard and beat him up there. But I didn't want to do that. I wanted to come to his own backyard and bring him down in front of his own crowd, a place he loves.

My career was a gift that I'm very happy about. I loved every step of it. I was blessed. I won all the titles and put my stamp on the sport.

I'm Yemeni, proud to be Yemeni. I'm public Yemeni number one!

I want to produce champions from Saudi Arabia and throughout the region.

I am excited by and impressed with Anthony Joshua, but Anthony has a long way to go. At first, I thought Anthony was similar to a Frank Bruno figure, but after a few fights, I realised he's nothing like Frank Bruno. He's very athletic.

I just feel proud when they say in 'Forbes' magazine that the highest-paid athlete is a fighter.

As a father, you become more responsible.

Boxing has lost its glamour and excitement. I'm going to bring it back.

When you are challenging for the world title, you've got to go into the lion's den to try and rip that belt away from the champion.

In my life, my religion comes first, and obviously, my family comes second.

When I used to leave behind my wife and kids and go into training camp for nine weeks at a time, I felt it, especially if you're having young children and leaving them literally within weeks of them being born.

When you become a world champion and you defend your title for five or six years, and you have fifteen defences of your title, and you round up most of the other belts - and you feel you're the best of your generation at the time - nobody can take that away from you.

During my career, there were times we were inseparable, and I can honestly say that if it were not for Brendan Ingle, I would not have achieved all I did in the sport of boxing.

There isn't a featherweight who can beat me.

I've won every title, and I've done everything in my division.

I know there is not a featherweight out there who I couldn't beat.

No, I've never been frightened before a fight.

I'm one of those very confident people who just forgets about fear and gives it to somebody else. I get into that ring, and I walk round, I hear my music, and then I start buzzing.

Yes, definitely, I've got so much belief in God, and I think that God's got so much belief in me.

I believe in my ability.

Losing will make me a better fighter.

I want the chance to show Barrera and the world that I am a true champion.

I still look back at the days in the early '90s and think, 'Boy, that confidence just came out in me strong,' and it was fantastic, the drama and the entertainment I brought.

I don't see anything remotely like me in boxing, past or future.

That's what a true professional is - a true world champion, so to everybody out there listening, especially the fighters that want to fight me... they'll get knocked out, sparko.

There's no bigger fight on the planet than Prince Naseem and Marco Antonio Barrera. What's bigger than that? This will be the greatest fight in the history of the featherweight division.

I just refuse to lose.

I've put myself on this pedestal from the start.

I want to be remembered as a guy who transcended boxing.

Great fighters get beat, and great fighters come back.

I do think I retired too soon. I just felt at that particular time in 2002, after winning a fifth world title belt, why not be one of the smart ones in boxing and get out.

I just felt I had done enough in the sport to put my stamp on boxing.

The Kelley fight meant that much because it's always when a fighter from this country goes over to America and proves himself, it's always make or break in a British fighter's career.

One thing that has irritated me in the sport of boxing since I stopped is I'm really surprised that no one has come along to excite me like me.

As a fighter, I recognise that the one thing we fight for is prizes. The one thing that motivates us is money. A lot of fighters do come back because of money. The biggest spur they have is financial, and thank God my finances were secure, and I didn't need to come back for that reason.

There were a lot of fighters who were better than me that got knocked out and stopped because they stayed in the game too long. That never happened to me. I don't know that feeling. I thank God so much that that didn't happen to me.

I carried the WBO belt for five years and defended it 15 times against 10 world champions.

I've knocked guys out in the 11th round before, late.

My idol, Muhammad Ali, got beat when nobody thought he would, and he came back and back to beat Joe Frazier.

I might spar with him, or I might teach him a few tricks, but even if there was $1 billion or £1m offered, I'd never get in the ring with another Muslim. It's against my principles.

At 19, I was European champion, and at 21, I was world champion. Let's just hope Amir Khan can follow in the same footsteps. I believe he can do it 100%; he's a fantastic talent.

I know I look arrogant, but I'm altogether a different person outside the ring.

I'm unbeatable and untouchable.
