On paper, Brazil have the best team in the World cup by far... but I don't know, they just aren't gelling properly at the moment, even though they are still winning. They need to get their passing game going better and iron out a few creases at the back.
If they get themselves in gear, they are pretty much unstoppable. Also, look at the depth they have! Guys like Juninho, Robinho, Julio Baptista, Gilberto Silva etc... all on the bench. Those guys would make any other team in the world!
