Bob Arum was Floyd Mayweather’s promoter for the first several years of Mayweather’s professional career, so he knows a thing or two about the fighter formerly nicknamed “Pretty Boy,” but who now uses “Money” as his moniker.

Arum on Thursday was asked to chime in on the upcoming Sept. 14 showdown between Mayweather and Saul “Canelo” Alvarez of Mexico. They will tangle in a junior middleweight title fight at MGM Grand in Las Vegas (on Showtime pay-per-view).

“I think Floyd is way too experienced for him,” Arum said during lunch at Off Vine in Hollywood. “And I wouldn’t be that surprised if late in the fight Mayweather knocks him out. That’s how I see it.”

The fight is being co-promoted by Mayweather Promotions and Oscar De La Hoya’s Golden Boy Promotions. Arum has an ongoing feud with Golden Boy, but Arum said he will order the pay-per-view feed, which will cost $64.95.

“Sure, Yom Kippur is over (the evening of Sept. 14),” said Arum, who is Jewish. “We do a breakfast at our house for over 100 people, so we’re going to buy the fight and it comes to less than a dollar a person.”

Arum and his guests laughed.
