Germany was superb, they are one of the big candidates.
I agree with Bolbol on this one brother Moon. Germany has a young team. They didnt even push themselves against Australia in my opinion, they played calm collected football so they dont tire themselves out since they know they have many more matches ahead of them before they meet one of the teams you mentioned!
Brazil im not sure will do good this year. Im surprised Dunga did not bring Ronaldinhio and this to me is just insane. Ronaldinhio's presence brings up the team spirit and play. I would love to hear Dunga's explanation on this! So i dont know about brazil
Spain is very solid team. Thats all im going to say

! VIVA ARGENTINA! lol hehe
Portugal always has a good team but somehow they lose out. C.Ronaldo is a great player and is going to have a great world cup, but he cant carry a team on his back like Messi. Barca vs Man U. VIVA ARGENTINA!
So as you see it just comes down to Argentina vs Germany..
wait....
then we have the Italiano's.... and i just dont like their attitudes on the field. I like the Brazilian/German and Argentians much better on the field.
England might not even come up.. they allready tied the US. Which is sad! Because America sucks to be honest. They dont have footbal culture, so they just dont have what it takes in my honest opinion.
Who else is there? I havent mentioned and you think has what it takes to win the most prized posession in human sports?
