Former undisputed heavyweight champion Mike Tyson has given some valuable words of advice to the newest kingpin of the division, Anthony Joshua (19-0, 19 KOs) - who holds the IBF, IBO, WBA world titles.
Joshua moved himself to the throne in April with an impressive stoppage win over former ruler Wladimir Klitschko - before a record crowd of 90,000 fans at Wembley in London.
Tyson, one of the biggest names in the history of the sport, was also one of the most financially successful fighters in the sport's history.
There are many who have called Joshua a "young Mike Tyson."
Based on his own personal experiences, Tyson learned the hard way when it came to being backstabbed by managers, promoters, women and even close friends. Tyson made hundreds of millions and also lost just as much money through foolish spending, bad investments and lawsuits.
In a wide-ranging interview with BBC Radio 5 live boxing's Mike Costello, Tyson discussed Joshua and what advice he would give the Olympic gold medal winner.
"Joshua has the potential to do a lot of things," said Tyson. "He's got the look and throws a lot of hard punches. But there is so much pressure on him. I was in Dubai and there are big posters of him there."
"The heavyweight championship will drive people crazy, you know that right? It's like a crown of thorns. Everyone wants to use you for something. It's like being the President of the United States. Joshua can't get the big head. He has to focus on fighting. When you start focusing on money, girls or whatever it is, it's going downhill. No religion, nothing, you can do those things when the fight is over. Let's see if he can handle that stuff.
"It's his time. I could be wrong, I'm not the gospel of boxing but he impressed me with Klitschko."
