Can Portugal win World Cup?

Pretty tough task for even favorites like Germany but this World Cup Portugal team looks quite balanced and their recent tournaments specially Euro 2012 Portugal were very unlucky to not win that semi final against crowned champions Spain.

Defense: 

Portugal have quite strong defense with two of Real Madrid player in that back 4 assures you a solid defense. Portugal defense performed pretty well against big teams as well in big tournaments.

Midfield: 

When you hear CRISTIANO RONALDO in any midfield's line up you surely understand how tough that team could be. Portugal also have midfielders like Moutinho, Veluso and young star Caravallho which could control midfield pretty well. Nani also is an option on wing with Quresma waiting to shine for Portugal as well.

Attack:

Ronaldo can be used in this area as well and this area without Ronaldo seems weak but as a famous quotes says: "Good attack wins you match but Good defense win you titles". So weakness in this area can be covered and by weak I m referring to fairly good attacker like Postiga, Varela etc.
