Oscar De La Hoya says that he is positive that Juan Manuel Marquez is capable of knocking out Floyd Mayweather Jr. on September 19 at the MGM Grand in Las Vegas. De La Hoya is under the impression that Marquez has more power in his punches than Mayweather. De La Hoya lost a split-decision to Mayweather in May of 2007 and says the "Pretty Boy" is not a hard puncher but his punches are very fast.

"Marquez can do it. If he hunts him down with one of the punches I saw him throwing, he can knock [Mayweather] out. [I am] 100% that Marquez wins.  Styles make fights and the style of Marquez is perfect to beat Mayweather. Marquez is intelligent, has the ability to counter but he is also aggressive, jabs and never gets tired," De La Hoya told The Record.

De La Hoya compared Mayweather-Marquez to some of the big fights of the past.

"This is like Taylor-Chavez or De La Hoya-Whitaker. This is a big fight and a big event. You are going to have a lot of people supporting Mayweather, but you will have everyone in Mexico and all of the Mexicans in the United States supporting to Marquez," De La Hoya said.
