Lance Pugmire, LA Times boxing and UFC reporter told Radio 5 Live how White will pay the pair of fighters $25 million each (£20.5 million) to face each other this summer.
He said: “Mayweather clearly believes he is the A side and rightfully so, I believe he is 49 and 0 and has dominated so many great opponents that he has fought throughout his career, so he’s going to want more money than that.
“But the fact that Floyd has come out today and said I’m un-retiring to fight Conor McGregor is something that should move the needle.”
Irish Olympic boxer and close friend to Conor McGregor, Michael Conlan claims that McGregor and Mayweather will fight in September. Conlan also says that the UFC icon with walk him out to the ring for his professional debut in Madison Square Garden next week.
