That's because compared to Brazil most of them aren't ready for prime time either.
France hasn't scored in four Cup matches dating back to the 2002 Cup. This is a tough tournament and some good teams always get humiliated. Nobody will laugh too hard until their own teams are well advanced, and it's very early in this tournament.
A lot of European pundits were surprised and dissapointed by the US match. There were quite high expectations for the US team this time around.
Hopefull you guys can manage to turn things around.
