It's quite difficult to predicts as we have 3 years ahead of us. As it looks now, I would say Spain. However, a lot of things can change. You need to look at the probable team roasters at that time. Brazil have some really talented players like Ganso and Neymar.
It is very difficult to say about that. Many of the things can be changed at any time...How ever, I'd like to say, Argentina will be the champion in world cup 2014.
My vote goes to Brazil, because he will be organizer 2014 football world Cup, and his much better team.
It will be Netherland, They are just unlucky when lost from Spain in final 2010...2014 is Holland time, Hup Hup Holland!!!
