WBC welterweight champion Floyd Mayweather Jr. is willing to entertain the possibility of a fight with Manny Pacquiao under one condition - the Filipino star would have to leave his promoter, Top Rank, and sign a contract with Mayweather Promotions. Mayweather face WBC/WBA 154-pound champion Saul "Canelo" Alvarez on September 14th at the MGM Grand in Las Vegas. Pacquiao takes on Brandon Rios on November 23rd in Macua, China.

Mayweather parted ways with Top Rank in 2006 and became a free agent. Over the years the boxer has often been critical of Top Rank and the time he spent under their promotional banner.

"The only way he's getting the fight with me is if he signs with Mayweather Promotions. He's got to give me fights with Mayweather Promotions. If he don't give me no fights under Mayweather Promotions, then he's not getting the fight. That's how it is working now, because the ball is in my court. The ball has been in my court. I have been the A side," Mayweather told Kevin Iole of Yahoo Sports.

Mayweather then made a claim that Pacquiao's adviser, Michael Koncz, attempted to cut Top Rank out of the negotiations for a Mayweather fight when the two sides came together during one of their failed discussions. Mayweather says the interaction with Koncz was recorded on video, which the boxer claims to have as proof.

"I went to Pacquiao at one particular time and I offered him $40 million and I told him, 'I will wire you $20 million within 48 hours.' He told me he wanted 50-50 and he got off the phone. Some guy named Michael Koncz came down here. I don't know who he is. He looks like a little weasel. He came down here, was in my gym and talked to me. He said, 'If you want the Pacquiao fight, you talk to me.' I said, 'What about Top Rank?' He said, 'I run all his business.' That's what he told me. I've got everything recorded, everything on film," Mayweather said.
