Manny Pacquaio,the Mexican problem,the Filipino pride.?

US coach Freddie Roach trained PACMAN like he never did before.Marco "the baby face asin" Barrera surprised by PACMANs power and KO'd on 11th round.Barrera accepted that he faced a boxer like a lightning he never met before.Again Barrera was lost to PACMAN on their rematch.PACMAN was lost to Morales by decision due to gloves he wear. But on their second and third rematch,Morales saw a real power of thunder from PACMAN and PACMAN KO'd MOrales.Does PACMAN has a chance in beating Juan Manuel Marquez in their rematch after PAC floored Maquez 3 times during their first match?
