Golden Boy Promotions President Oscar De La Hoya is warning experts that Floyd Mayweather Jr. (44-0, 26KOs) looked very impressive on May 4th because Robert Guerrero had the wrong game plan and fought flat-footed for twelve rounds, and that allowed Mayweather to stay on his toes and move in and out. De La Hoya expects Saul "Canelo" Alvarez (42-0-1, 30KOs) to provide a much tougher challenge on September 14th at the MGM Grand in Las Vegas.

"I was impressed with his footwork against Guerrero, but then again he fought Guerrero. But Guerrero fought the wrong fight with no game plan and that's the truth. Guerrero is one of the best fighters that I've seen in the last few years but he fought with the wrong game plan. And that's what I mean when I say 'he fought Guerrero' - a flat-footed Guerrero. Anybody could have outboxed Guerrero that night. But I know why he looked good, because Floyd Sr. was back in his corner and Floyd Sr. makes him work hard and get in great shape," De La Hoya said.

"But being in great shape and working out is not going to help you out against Canelo, who is young and strong and fast and in the fight of his life."
