Gebhard my friend, we can discuss about this for the all day, but I will try to tell you what I am thinking (sorry for the English)
Dunga was an excellent and hard worker defender; he was the captain of Brasil in 1994 USA WC. At the time, no many players played in Europe, but now among the 23 players called for SA 2010 only three players play in the National league in Brazil. The rest plays in Italy, Spain and German.
Brazil also was known as an offensive team that never had a good defence line but for the last 3 years, Dunga is trying to develop a European style of futebol, very defensive, and without offend my Europeans fellas, UGLY style of play that does not reflected the our way of play. Nevertheless, it is working, since Dunga is the coach Brazil has won every competition and qualified three rounds in advance for the WC. Today Brazil has one of the best defensive line in all time, with the best keeper from Inter de Milan, Julio Cesar, nice defenders like Lucio, Juan , but the midfield and the attack is very average-poor...something that was a trade mark of Brazil the ATTACK..... is not that good today, I can’t see Robinho do much (I do hope I am wrong)
About Ronaldinho: IMO he should be there for sure.
Brazil has not a good Mid-field, someone who can organize and prepare the strikers and in the same time become a striker himself, he is the kind of player who you just have to unleashed on the field, if you try to tell him what to do is not going to work, and this was the problem of Ronaldinho in the national team....
Now, one week from the start we can only pray and hope that we will add a sixth star on the left chest of the canary yellow shirt.
