I think Belgium has a nice group with young talented players on their prime.
Maybe only Brasil and spain attacks are better... but one thing is to look better on paper and another is to play as a team on the field. I think the belgians will reach far.
On the othher hand, Argentina is full of known names in attack but seem to be having trouble gelling together. Germany looked dire, they need more on midfield and i think Khedira is being one of the reasons. Maybe that generation is burned i dont know.
Portugal have Gaynaldo..who seems to be more in sync with his teammates than Messi with his. I think the argentina players are mentally too overreliant of messi, and are always looking to him to do something instead of supporting him and work themselves their part.
Spain , i thunk they have really good talent in their midfield and Costa seems to be in form. I also think they will reach far, if not win the thing.
England is always a mystery to me. Great league, great players, but seem to have difficulties going far.,
