Mayweather flashes wads of cash in Rolls-Royce after $9mn, 2-minute destruction of Nasukawa (VIDEO)

Floyd ‘Money’ Mayweather has been showing off some of the financial fruits of his recent labor by flashing wads of yen he presumably earned when destroying Japanese kickboxer Tenshin Nasukawa in their New Year’s Eve bout.

The boxing great, 41, plowed through the 20-year-old just 140 seconds into their exhibition bout in Saitama.

The fight was decried as one of the biggest mismatches in sporting history as boxing novice Nasukawa faced the former five-weight world champion who was undefeated in 50 professional fights.

He’s been showing off his earnings in typically flashy fashion, posting an Instagram video with two of his fleet of luxury cars, including a Rolls-Royce laden with wads of yen bills inside.

Mayweather has racked up around $760 million in career earnings according to Forbes and has never been shy to flaunt his immense wealth .  

He frequently takes to social media to show off his luxury lifestyle including set of mansions and array of luxury motors.

He reportedly spent a whopping $5.3 million in just one Los Angeles shopping spree toward the end of last year.

There are rumors that the US fighter is looking to bolster his already impressive earnings with a lucrative bout against Russian MMA star Khabib Nurmagomedov.

The UFC lightweight king’s agent, Ali Abdelaziz, recently said that Mayweather had been contacting him and was “begging” to fight Nurmagomedov.
