Why Mexico did not win vs USA in soccer?

It's always the same excuse. Mexico played well, but they just had bad luck. The reason Mexico did'nt win is because they do not have good attacking players up front. They lack creative players. Cuahtemoc is clever, but he does not have the physical speed or strength. I hate that Mexico always depend on players who are good headers like borgetti and Fonseca. They can't always depend on free kick or corner kick goals. The game is about scoring goals not about keeping the ball and doing nothing with it. I'm sorry to say that at this pace U.S will win the world cup before Mexico. I hope they do, so Mexico can receive a wake up call.
