Arum:

“If Mayweather fights the way he did against [Shane] Mosley, Manny will not only win, but he will knock him out.”
And Manny on Floyd's win:

“If I can hit Mayweather like that, I will finish him off. I would continue the attack in a way that Mosley did not. I will attack until Mayweather is gone.”
