UFC president Dana White is expected a very big pay-per-view buyrate for the proposed pay-per-view boxing fight between company superstar Conor McGregor and retired five division world champion Floyd Mayweather Jr.

White, who already reached a deal with McGregor on his side of the fence, is now hoping to reach a deal with Mayweather, who retired from the sport in September 2015 after dominating Andre Berto over twelve rounds.

White told a group of reporters outside Citi Field in New York, that he believes the two athletes - based on their popularity and their ability to sell pay-per-views - should split the money down the middle, 50-50. The chances of a 50-50 split are pretty thin, when considering that Mayweather refused to budge from a 60-40 split when it came to his 2015 showdown with Manny Pacquiao.

“We haven’t even got there yet,” White said, according to MMA Fighting. “We haven’t even talked percentages yet. … Floyd can think whatever, but the machine that the UFC has and Conor McGregor alone is a machine by himself. I think that 50-50 is pretty fair.”

White gives the fight a "75% chance" of taking place, and beieves the contest is going to do tremendous business on pay-per-view. Mayweather-Pacquiao holds the record with 4.6 million buys.

At the moment, White says there are no issues in dealing with Mayweather and his adviser, Al Haymon.

“I think this thing does, conservatively, between 2.5 and 4 million buys,” White said. “Other people think more. … And this thing will kill it, globally. Conor McGregor and the UFC are huge in Brazil, huge in Australia, massive in the UK and other parts of Europe.”

“I’m very bullish on this fight. I think it happens. These guys are gonna have to come up with something way out of left field for this fight not to happen. We’re ready to go. And I think what we’re looking at in the deal is as fair as fair can be. You’ve gotta understand, Floyd and [Al] Haymon and that group are used to dealing with the scummiest human beings on the planet Earth. I think it’s a little refreshing working with us. And I’m not just being arrogant. They’ve said that to us. I can see it getting done.”
