Much has been made about the popularity of Saul “Canelo” Alvarez in his native Mexico. If you listen to executives from Golden Boy Promotions, they’ll tell you that Alvarez is the most popular fighter there  today, that he is treated like a rock star.

Floyd Mayweather Jr. isn’t so sure about all that.

“Among Hispanic/Mexican/Latin fighters, I don’t really know who has the biggest following,” Mayweather said. “But if I had to say so, I would say probably (Juan Manuel) Marquez because he has accomplished more and done a lot for the sport of boxing. So I don’t support the thought that ‘Canelo’ has a bigger following than (Marquez).”

Mayweather (44-0, 26 KOs) and Alvarez (42-0-1, 30 KOs) will tangle in a junior middleweight title fight Sept. 14 at MGM Grand in Las Vegas (on Showtime pay-per-view).
