Roy Jones Jr has no doubt who would have come out on top in a fantasy match-up between Floyd Mayweather and Sugar Ray Leonard.

Boxing legends Mayweather and Leonard both have the honour of being five-weight world champions, but it is perhaps their respective times at welterweight where they were each at the peak of their powers.

Mayweather defeated the likes of Manny Pacquiao, Shane Mosley and Juan Manuel Marquez in the 147lb division, while Leonard became undisputed welterweight champion after wins over fellow ‘Four Kings’ icons Roberto Duran and Thomas Hearns.

It has often led fans to debate how a clash between Mayweather and Leonard would have played out were they to meet in their primes at welterweight, and Hall of Fame inductee Jones is certain what the result would have been.

Speaking to All The Smoke Fight, Jones couldn’t see any possible way that Mayweather would have been victorious.

“To me, people don’t give him enough credit. People always say ‘Well Floyd would have beaten Sugar,’ no baby, Floyd is not as nearly as mean as Sugar was.

“How? [would Mayweather win]. How you going to keep him off him? Sugar is a dog. People don’t understand. Just because his name’s Sugar don’t mean nothing! Sugar is a dog, people don’t give him enough credit for that.”

Jones is extremely confident that Leonard would have got his hand raised, something which actually happened when he took on Mayweather’s father Floyd Sr back in September 1978, claiming a 10th round stoppage win.
