After announcing a September bout against Andre Berto last week Floyd Mayweather should be busy preparing for what is likely to be his retirement fight.
Instead though, it looks like the ongoing war of words with female UFC superstar, Ronda Rousey, continues to weigh on his mind.
Speaking to ESPN's Sports Center this week, Floyd Mayweather couldn't help but stir up the bad blood.

“I’ve yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes,” Mayweather explained. “When she can do that, then call me.”
With Ronda Rousey gaining plaudits as the biggest fighting star i nthe world right now it looks like Floyd Mayweather wanted to make clear just how far ahead of the rest he is when it comes to his bank balance.
The friction between the two began back in 2014 when Mayweather claimed he didn't know who Ronda Rousey was, even suggesting he thought he was being asked about a man.
The UFC star hasn't sat back and allowed Mayweather to have things all his own way though. Rousey used the recent ESPY Awards to land her latest verbal blow on the fighter, making reference to Mayweather's checkered history with domestic violence.
Not all bad
Floyd Mayweather isn't the kind of man to let someone else have the last word so Rousey had to be expecting a reaction.
But, whilst the boxer looked to emphasize his position at the top of the fighting pedestal, he did have to uncharacteristically kind words for his UFC rival, too:
"A while back I didn’t know who Ronda Rousey was, so I’m pretty sure she got upset. I want to say congratulations to Ronda Rousey and the UFC."
"You guys have done a tremendous job and I’ve won probably six or seven ESPYS for Fighter of the Year. And I truly believe she deserves it. Congratulations to Ronda Rousey.”
