They did not play a horrible game. They were merely beaten by the better team.
France cannot beat Germany, it is an impossibility. You are betting on the wrong team here if you think the frogs are going to win the World Cup in Germany. When they played Brazil I gave them a 60% chance of winning not because they are better than Brazil but because the Brazilians have just a historical psychological problem overcoming the frogs. On the other hand France has the same problem beating Germany in a World Cup in fact France has a problem beating any Power house soccer nation except Brazil, which kind of odd because most teams in the world have problems beating Brazil.
Brazil will always remain the best soccer nation on the planet and the record clearly shows it. There is always another time for Brazil and another opportunity to win yet another world cup, so far they have five and they will have their sixth and seventh.
