Tyson Fury says he is "done" with boxing after his victory over Dillian Whyte and he intends to retire as an undefeated champion.
Fury record the 32nd win of his career when he beat his fellow Brit in the sixth-round in front of 94,000 people at Wembley last week.
After the match he spoke in the ring, declaring that it was his last fight.
It is a claim Fury has often made following previous fights, and most analysts believe a unification fight will test his resolve, but Fury - for now - if adamant he means it this time.
"This is the truth, the gospel truth, nothing but the truth - I'm done," he told Piers Morgan Uncensored.
"Every good dog has its day. Like a great Roman leader said, there will always be somebody else to fight.
"When is enough enough? I'm happy, I'm healthy, I've still got my brains, I can still talk. I've got a beautiful wife, I've got six kids. I've got umpteen belts, I've got plenty of money. I've got success, fame, glory. What more am I doing it for?
"Boxing's a very dangerous sport, you can be taken out with one punch as we've seen on Saturday night, and it only takes one unlucky blow and you may not get up off that canvas.
"I'm quitting while I'm ahead. I'm undefeated, only the second man in history to retire undefeated heavyweight champion.
"I'm very, very happy and very content in my heart with what I've done, what I've achieved.
"It's not about money for me. A lot of people in this world, everything is about money, and more money and more money. I've got enough money. I've got enough of everything I need.
"I'm a very simple man. I drive an 07 VW Passat. I'm a very normal person, I don't need tons of money to impress everybody."
There is a lot of interest in a potential fight between Tyson Fury and Oleksandr Usyk or Anthony Joshua, with many believing either could be the most lucrative bout in history.
Fury, though, has reiterated that money will not be any attraction to him, saying: "It's not worth it.
"I've got a family to raise. I have four young kids to raise and two older ones.
"I've been away for the last 10 years on the road, all over the world, travelling for boxing. When do I get time to be a father or a husband, a brother, a son. I need this personal time.
"The fans will always want more, they are always baying for more blood. But at the end of the day I don't have anything more to give. I've given everything I've got. I've been a professional (for) 14 years, I've been boxing over 20 years.
"My time is to go out on a high. I always said that I wanted to walk away on top of the sport, and do it on my terms, and I didn't want to be the person who said 'well, I should have maybe retired two years ago' or whatever.
"I just wanted to walk out on top, go out with a bang. Nearly 100,000 at Wembley, with a knockout performance - they will not forget the Gypsy King in a hurry, and no amount of material assets or money will make me come back out of retirement because I'm very happy."
