Former two division champion and Showtime Boxing expert analyst Paulie Malaignaggi views Floyd Mayweather Jr. vs. Conor McGregor as "a joke."

He gives McGregor no chance of beating Mayweather in a boxing match.

That said, Malignaggi believes the potential fight would do tremendous business on pay-per-view and feels the fight would have a strong chance to crack the PPV buyrate record set in 2015 by Mayweather's mega-fight with Manny Pacquiao - which generated 4.6 million purchases.

A few days ago, UFC President Dana White revealed that he reached an agreement with McGregor, as far as the financial terms, to do the Mayweather fight. Now White will have to negotiate a deal with Mayweather's side.

"The McGregor side is done," White said. "I'm not saying the fight will happen but I got one side done and it's time to work on the other (Mayweather). If we can come to a deal with (Al) Haymon and (Floyd) Mayweather, the fight's going to happen."

McGregor has been the UFC's most popular fighter and among its top money spinners while the 40-year-old Mayweather retired in 2015 with a 49-0 record including 26 victories by knockout.

Malignaggi realizes that both sides have a ton of money to gain by making the fight - even though it's viewed as a mismatch by a lot of experts in the combat sports community.

"They are both very dangerous in their own elements, but this is only the element of one of the fighters," Malignaggi told BBC Radio Five Live.

"I think it has the chance to really succeed Mayweather-Pacquiao, I really do. The boxing community are really the only ones that think this is fight is a joke. The boxing community at the end of the day is really small, it's niche.

"It's not really going to persuade any non-boxing people or any MMA people to really think that the fight is not a good fight. I don't knock this fight for happening. It makes all the sense in the world for so many reasons - for both fighters, for the business, for their well-being and of course just for the general public interest and what not.

"Putting those feelings aside and speaking just from a totally tactical combat sports standpoint, the fight is an absolute joke. It is, but I don't want to think about it that way. I want to think about the fact that the event is going to be big, the promotion is going to be big and the press conferences are going to be fun. The entire event will be fun as long as people don't go into it with this high expectation that fight night will bring this big explosion. Because it won't."
