Brazil struck twice through Weverson and Paulinho in a space of six minutes in the second-half to trail past Germany and seal a semifinal date against England.
Germany coach Wueck congratulated Brazil but was clearly unhappy with the USA referee, as he claimed that a legitimate penalty was denied before the Selecao juniors got the lead in the 77th minute.
"Did you see the game? I think you can answer the question alone. Just look at Jan Boller's (bruised) eyebrows. Before they took a 2-1 lead. Just look at his eyebrows. He had a cut in his eye, and it was a clear foul. The difference was the referee I think. We had a chance to equalise but we were not so lucky today."
"Before every World Cup game, each team gets instruction from the referees that every elbow in the face is a clear foul. It's a red card, and here it's not a foul! I don't believe it," he was furious.
