Paraguai has a very decent team imo, i'd rate them more or less in the same level as Usa. We had two losses in the eliminatory, one of them was against Paraguai :P And you shouldn't forget that Cabanas ( aka, the dude who completely trashed my Flamengo in Maracana back in 2008

) took a bullet in the head and won't be able to play the WC. That's a major problem for them
Netherlands till now is the team that made me most worried, Germany was awesome but they were playing Australia and Italy reminds me of Milan currently, I don't think they'll get past the quarter finals.
Ghana is the best african team by far till now, Ivory Coast could go far, but got bad luck in the group draws, i'm thinking they'll be out by sunday.
Brasil is really based on defense and counter-attacks since Dunga became the coach, and we're quite good at it*. In that friendly with Portugal that they were attacking like crazy, we managed to win by 6x2

I pity Spain if our paths happen to cross.
*that doesnt mean i like it, i'd rather see a team like 82, even if we lost that cup
