He is the man who taught Floyd ‘Money’ Mayweather the silky skills that helped him become boxing’s pound-for-pound king.

And now at the age of 64, Floyd Mayweather Sr is helping nurture the heir-apparent to his son’s crown, ‘New Money’ Devin Haney.

Eighteen-year-old Haney is unbeaten in 16 professional fights and of one of boxing’s hottest prospects.

He is being mentored by ‘Money’ and could feature on the undercard of the 40-year-old’s upcoming bout with Conor McGregor in Las Vegas.

The 18-year-old has previously trained alongside the unbeaten American at his Las Vegas gym. And he recently showed why he is tipped for greatness by displaying incredible hand speed while doing pad work with Floyd Sr.

A video posted on Twitter by UFC fighter Soa The Hulk Palelei shows Haney throw a remarkable combination that sees him land 21 punches in only six seconds.

And though there is 46 years between them, Mayweather Sr shows no sign of losing his own ring skills and he keeps up with Haney during the incredible flurry of punches.

The 64-year-old has trained some of the finest boxers of the last 25 years, including Britain’s Ricky Hatton and the ‘Golden Boy’ Oscar De La Hoya.

And Mayweather Sr has tipped Haney to emulate their success and become a world champion, dubbing the prospect a ‘carbon copy’ of his son and a Hall of Fame fighter in-waiting.

Floyd Jr, too, had high praise for the 18-year-old following Haney’s spell in his gym. ‘After seeing him work in the doghouse,’ Mayweather said at the time, ‘I know he’s going to be an unbelievable professional.’

Haney even got the chance to spar the unbeaten 40-year-old last month as Mayweather prepares to fight McGregor.
