Two months after fighting and defeating Marcos Maidana in a welterweight fight last May, undefeated boxer Floyd Mayweather Jr. is believed to be fighting Maidana again on his next fight this September.

In an interview on Sunday night with LaTen Media, Mayweather announced that he would be going against Maidana again.

In the video interview above, Mayweather said "Sept. 13, back to business, Marcos Maidana-Floyd Mayweather, part II. And then in May, I'm fighting in May and I'll have a big surprise for ya'll."

But Maidana's manager Sebastian Contursi told ESPN that there is no deal yet but that he is still talking with Al Haymon who is the adviser of the two fighters.

"Still in the talks. Nothing confirmed on our side. Hopefully, we'll have a decision made in the next four to five days," Contursi added.

Maidana, on the other hand, posted on his Twitter page and said "REMATCH in the talks. Respect for @FloydMayweather man of his word, yet only fist talk in the ring. #LATINPOWER." 

As for the pay-per-view forecast, ESPN said that the previous fight of the two boxers generated around 850,000 buys, a far cry from the 2.2 million that Mayweather had from his fight last year with Canelo Alvarez. 

The same report noted that Mayweather has set the bar high for his pay-per-view success and that he was beating his own records.

"Last I checked Floyd Mayweather is the only one making the kind of money he is making. He has no peers. He has zero peers. There is no other boxer or athlete in the world generating that kind of revenue. Love him or hate him he is the money machine," Mayweather Promotions CEO Leonard Ellerbe told ESPN.

Mayweather has been named as the highest-paid athlete in the world by ESPN and Forbes.

But ESPN also noted that Maidana might get the nod of Mayweather only because he has run out of opponents to fight since there are no talks with Manny Pacquio's team. It added that Pacquiao's pay-per-view records have also dropped because they were unable to seal Mayweather as an opponent for Pacquiao's November fight. 

It can be remembered that Maidana lost to Mayweather in a 117-111, 116-112 and 114-114 result but reports noted that it was one of the latter's toughest fights since Maidana gave him a very physical battle; one of the worst in his careers.
