Former three time welterweight champion Antonio Margarito says WBA champion Shane Mosley has the power to beat Floyd Mayweather Jr. on May 1 at the MGM Grand in Las Vegas. Margarito wants to fight some of the big names at 147-pounds. He makes his ring return on May 8 against Carson Jones in Mexico.

Margarito is unsure if Mosley will be the actual winner because he doesn't know which version will show up against Mayweather. Margarito doesn't know if the Mosley who knocked him out will show up, or the Mosley who struggled with Ricardo Mayorga will enter the ring.

"I feel that Mosley has the power to beat Floyd, but since Mosley has looked good in some fights and not too good in others, I'm not sure which Mosley is going to show up," Margarito told AOL's FanHouse.
