To be fair, that was an All-Série A squad, not the actual Brazil squad. And the only reason we had so many youngsters was well...It was the Olympics.
But i agree that Scolari was a huge step back, his style is obsolete and not appropriate for modern football. Menezes on the other hand was like having nobody, he was anything but a manager. Either way, if Brazil ever stands a chance of winning the Confederations or the World Cup, it'll be by individual talent, the collective is beyond shit and we don't have enough time/a real manager to make it work.
