Former world champion Carl Froch fears that Floyd Mayweather is putting himself in position to potentially ruin his entire legacy if he underperforms, or even loses, against Youtube star Logan Paul in their upcoming exhibition clash on June 6 in Miami.

Mayweather, 44-years-old and a five division world champion, retired from the sport in August of 2017.

The 26-year-old Paul has only had a single pro fight, but he will have a significant size and weight advantage in the contest.

Mayweather walked away from the sport with a perfect 50-0 record and is widely regarded as one of the best boxers in the history of the sport.

Most experts are predicting a one-sided contest in favor of Mayweather - but at the same time anything can happen when the right punch lands.

"We could find out if Logan Paul can fight a little bit when he's in the ring with Mayweather," Froch told Sky Sports.

"Mayweather is going to be incredibly hard to hit. Logan is heavier and slower and although Mayweather hasn't competed at any level for so long, it really doesn't matter. It's like me playing an old tennis player who has not played for years. I play tennis quite a lot now, but I just know I'm getting beat by the pro tennis player, who has been retired for two years, because they are just too good.

"Mayweather should be far too good for him, but it's exciting and it's got your interest, because Logan Paul is so big, Mayweather has been retired for so long, and you do think, 'Oh what if Mayweather ruins his whole legacy by losing to a YouTuber?' That's the appeal. That's going to make you watch it.

"I don't want to say he's got a chance, but he has got a chance Logan Paul, because he looks like he can shape up quite well. He's had a couple of fights and he's so big. Mayweather could end up making a mockery of his whole career. If he gets caught and gets put down, it will be embarrassing. If he loses, he might as well get a one-way ticket to Australia."
