Former middleweight great weighs in on clash between Pacman and Money

Manny Pacquiao needs to knock out unbeaten Floyd 'Money' Mayweather Jr. in the first six rounds of their May 2 super fight or the Filipino star will lose on points, Marvelous Marvin Hagler predicted in Shanghai on Wednesday.

"Anywhere from one to six, I would go Pacquiao, and then after that I believe that it's got to be Floyd Mayweather because of his boxing techniques," said the former undisputed middleweight champion of the world.
