manny by a country mile. mayweather is great but he is beatable!! manny would destroy him. hatton took mayweather a long way and looked like winning, manny p is more disciplined, trains harder and can take a punch. i doubt mayweather would be able to defend as well as he has against mannys attack.
BUT... mayweather i must say is class to listen to and there is nothing wrong with abit of confidence but i do think he needs to think about what he says b4 this fight cos when he loses hes gonna look like a tool lol.
