Manny Pacquiao knows a thing or two about fighting Floyd Mayweather is a so-called “superfight.” The two fought in a much-hyped, mega rich, and largely boring affair in 2015. As Mayweather prepares to unretire in order to fight UFC star Conor McGregor at the end of August, Pacquiao laughed off the idea that the latest version of the “Fight of the Century” would be even slightly competitive.

“McGregor has no chance in this fight,” Pacquiao said, according to Dan Wetzel of Yahoo! Sports. “In fact, it could be very boring.

“There is no way he will be able to land a meaningful punch on Floyd,” Pacquiao said. “How could he? He has no professional experience in boxing.”

McGregor has zero professional boxing experience, although he does have a canon of a left hand that has resulted in numerous MMA knockouts. However, he opened up at a 25-to-1 underdog in most sports books. That number has since dropped to around 6-to-1, depending where you look. Mayweather, meanwhile, is a perfect 49-0 in his pro boxing career and a prohibited favorite in the fight.

Pacquiao says that real boxing fans will save their money to buy the Gennady Golovkin vs. Canelo Alvarez pay-per-view that takes place just three weeks after the Mayweather/McGregor bout.

“The real fight and the best fight is Golovkin vs. Canelo,” Pacquiao said. “The best versus the best. That’s the fight I will be watching.”

Pacquiao also continues his career this summer, as the Filipino legend will take on Jeff Horn in Australia on July 2, where he will defend the WBO welterweight title.
