Brazil is going to destroy this WC, such a good squad they have, they might be missing a true organizer in midfield or a pure and world class 9 (Diego Costa would've been this 9) but do they even need them? Brazil plays a counterattacking football so all they need are speedy forwards (which they have) and players with good long ball pass (which they also have). GK is probably their weakest point, Julio Ceasar is prone to a howler or 2 which against a really good team you can't afford, so we'll see.
To me they are favorites, though.
They're so favourites hell will break loose when the Maracanaço 2 happens
