Five key facts on Floyd Mayweather who beat Manny Pacquiao in the richest fight in history on Saturday:

+ Floyd Mayweather, 38, is now unbeaten in all his 48 professional fights and the welterweight and following his triumph over Filipino folk hero Manny Pacquiao has now gone down as one of the greatest fighters in history - admired for his ability to dodge and weave around confused opponents. He says there will be just one more fight before he retires.

+ Mayweather has an estimated net worth of between $280 million and $300 million and some forecasts say he will pocket up to $200 million following Saturday's Las Vegas clash. The American, whose nickname is 'Money', loves to show off his wealth which includes a Las Vegas mansion, a huge collection of diamond and gold watches, two $40 million private jets and a fleet of supercars. He has a personal barber even though his head is shaved.

+ Mayweather is also often seen with beautiful women at his side. But he has multiple convictions for assaulting women over the past dozen years and served two months in jail for the most recent. Boxing's world bodies have never sanctioned him for the offences. Last year some boxers who work out at his Las Vegas gym sued Mayweather over the training conditions which allegedly included making fighters go 31 rounds without a break.

+ Mayweather last lost a fight when an amateur in the semi-finals of the 1996 Atlanta Olympics. US officials protested that a Bulgarian boxing official had pressed judges to give the fight to Bulgaria's Serafim Todorov. As a professional, Mayweather has fought in the super-featherweight, lightweight, light welterweight, welterweight and light middleweight divisions. He briefly retired in 2007.

+ Now Mayweather says he will retire after one last fight in September as he has nothing left to prove. That will be his 49th combat and will fulfill a moneyspinning six-fight deal with the Showtime television channel. "My last fight is in September. I'll do that and I will hang it up," Mayweather said again after beating Pacquiao. But there are still those who believe he will be tempted to go for a 50th professional fight without being beaten.
