I have watched the fights of valero and I think he won't be able to knock out Pacquaio. Valero's style is the same as Pacquaio's style 7 years ago when the Pacman was still fighting in Blow by Blow.

However, Pacquaio can't be too confident. Valero has power in his punches. Valero can deliver a lucky punch and this may ultimately change the tide for Pacquaio.
