I'm 95% sure Argentina won't win again. Too basic to think what worked last time will work again. The motivation factor will be decreased and many players are 4 years older, in a negative way.
Spain are undisputed favourites and clearly the best team on paper in terms of both quality and cohesion. Question is if DLF will want to disturb the peace in the XI by bringing in better but 'newer' players like Joan Garcia.
Egos of France will probably destroy themselves.
I'd put England's squad higher if it wasn't for it being.. England.
Portugal have one of the best squads but might be held back by Martinez.
Germany can be dangerous if they can get a hard working and focused squad rather than relying on big names.
Brazil I see no chance of winning.
