Last Wednesday, Conor McGregor, former UFC lightweight and featherweight champion, sent a tweet from his official Twitter account saying that a rematch with Floyd Mayweather would be 'interesting, no doubt'.In the same tweet, he said that he had a real chance of winning the fight, but made a poor decision at one point during round eight."I spoiled it with the rush right hook here,” McGregor tweeted. “The angle was made. He was in the dirt. I just had to set correctly into my feet and fire. Rushing the right hook I lost balance on my back hand. Great boxing fight! A rematch will be interesting no doubt.”However, in a recent interview with TMZ, Mayweather made it seem as if he wasn't really interested in a rematch with the Irishman.In the interview, he made subtle references to his $18m watch when questioned about a rematch, possibly hinting that he doesn't need the money. "Everybody wants a rematch with me. Don't worry about that," said Mayweather, speaking to TMZ.It has been reported that Mayweather and McGregor earned a collective $130m, with the former taking approximately $100m of the payout.Mayweather doesn't seem too keen on the idea of a rematch with Canelo Alvarez either.Their fight was back in 2013, with Mayweather winning via majority decision. 

In the same interview, Mayweather also said: "Yeah, yeah, yeah ... everybody’s saying something. I don’t worry about that. I already made over a billion! You already know that!

“I’m not worried about all that my man. Floyd is undefeated. Nobody can beat me. You already know that, man!”

The American's last fight came against Japanese kickboxer Tenshin Nasukawa.

The event was described by many as 'laughable' due to the nature of a former world champion boxer taking on a kick-boxer in an event in which kicking was banned prior to the bout. Mayweather won the fight in a first round TKO.
