We are all just saying the same thing over and over. Non-latin European teams (Germany and the Netherlands here, but also England, Belgium and Switzerland) play a balanced planned out game. South american teams played in a more improvised way. It has been like this at least in the last 25 years that I have been watching football and understanding a bit (I was 2 during Mexico 86).
Regarding this world cup, Argentina is playing dull? How come? It may be playing badly, but it is playing offensively, sometimes even more than it should. I think it is by far the most offensive team on the cup.
I like how the Netherlands is playing, but I do not like their style nor Germany's. Being the favorite and with score 0-0, they are already playing defense and counter strike by recovering in the midfield. It is effective, but that's what I call dull.
Brazil is playing horribly, but still, I think they may beat Germany and win the final even without being the team that plays best. Brazil has that way of winning, and they are the home team.
