We all (myself included) love the idea of the 1970 or 1982 Brazil teams just trying to outscore everybody with the most talented offensive players in the world, but Brazil is not that team anymore. Joga Bonito is the stuff of myth and legend, not fact.
Don't get me wrong, Brazil is still a very talented squad, with several players who can really turn on the flare when necessary. But they play a very practical formation with two holding midfielders and an emphasis on defensive positioning and a lot of running.
Brazil are an excellent squad, and Dunga is certainly one of the best managers at this tournament, but don't expect an 6-5 matches from this team. In fact, I would get used to 2-1, we may see it from them another five or six times.
