I am never underestimating Pacquiao ever again and I think that he will a strong UD. Although Clottey will physically be the biggest fighter Manny IMO has faced I dont think that he will be able to hurt Manny and he will not be able to handle all of the punch combinations that Manny will unload. I expect another strong performance from manny, and lets hope to god that he faces the winner of Mayweather-Mosley.
