Floyd Mayweather’s exhibition fight against Tenshin Nasukawa descended into a farce.The American arrived late to the event at the Saitama Super Arena in Japan and needed just 140 seconds to defeat the 20-year-old kickboxer.Mayweather knocked Nasukawa down three times before the Japanese’s team threw in the towel."It was all about entertainment - we had a lot of fun," Mayweather said after the fight, per BBC Sport."They wanted this to happen in Japan, so I said 'why not?'"The 41-year-old reiterated that he remains retired from boxing.But it wouldn’t come as a surprise if he followed this up with several more exhibition contests.

Mayweather flaunts his $9m earnings

That’s because Mayweather earned $9 million for his involvement in the New Year’s Eve event, which was promoted by Japanese mixed martial arts organisation Rizin.

It was an easy payday for the American and he couldn’t wait to flaunt the cash after the win.

Mayweather has posted a video on his Instagram Story showing some of the $9m worth of Japanese yen, which comes to ¥982million, he made against Nasukawa.

It’s a video that hasn’t gone down well with a number of fight fans who are rather fed up with Mayweather flaunting his wealth.

“Such a pity that for some unknown reason he decided to combine the greatness in the ring with pathetic pimp behaviour out,” Twitter user @chigiquinto wrote.

Mayweather was boasting about the money that he was about to make before the fight.

“What if I told you I was making $9,000,000 for 9 minutes of sparring in Tokyo Japan would you do the same if you were me? I like to call it a 9 minute walk thru,” was the message accompanying a post on his Instagram page.

It’s easy to dislike Mayweather’s boasts but this is the position he now finds himself in after an impeccable professional career.

He holds a 50-0 record in the sport and is considered by many to be the greatest pound-for-pound pugilist of all-time.

If promotions are going to pay him millions to compete in unofficial contests that don’t require any training, we’d better get used to it.
