If there’s one thing that Floyd Mayweather loves above anything else, including boxing itself, it’s making money.The 41-year-old is not just a boxing legend; he’s also a smart businessman - hence why he has amassed an estimated net worth of $1 billion alongside his flawless professional record of 50-0.But despite his vast personal fortune, Mayweather is always looking at ways to boost his already massive bank balance.Last month, for example, he splashed out $2,000 on Mega Millions lottery tickets in the hope of winning the $565 million jackpot - as if he needs the cash.Many people saw this as an act of pure greed - and they might have a point - but you don’t have $1 billion in the bank unless you are motivated by making cold hard cash.Mayweather also loves a big-money bet from time to time. In October 2017, he put $50,000 down on a college football match and pocketed a cool $95,000 in return.Two years prior to that, he put a bet on Tyson Fury to beat Wladimir Klitschko - despite the fact he’d never seen the British heavyweight fight before.“I’ve only seen Fury fight once and I'd never seen him before but I bet on him because it was good odds,” he admitted after winning his bet on Fury.

Fury hasn’t forgotten about this - and reminded Mayweather about the wager after bumping into the legendary boxer at a LA Lakers game earlier this week.

After Mayweather wished him good luck for the Deontay Wilder fight on Saturday night, Fury said: “Thank you. I heard you had a big bet on me against Klitschko - good stuff! He knows a winner when he sees one.”

Mayweather laughed before wishing Fury good luck and admitting: “I’m proud of you”.

Fury and Mayweather were at the Staples Center, venue for the Wilder fight this weekend.

It’s unclear whether Mayweather will have another flutter on Fury, but he could win big money again if he does.

Fury goes into the fight as the narrow underdog with the bookmakers, having only fought twice since that victory over Klitschko three years ago.

Wilder, who also boasts an undefeated record like Fury, has won five nights since then and is confident that he will retain his WBC heavyweight title this weekend.
