Yes, the USA were robbed. Not only was a perfectly good goal disallowed, but even if the striker had missed, there was a blatant foul on Clint Dempsey, which should have seen a penalty and a card for the Serbian defender, who obviously does not know the difference between football and wrestling.
In the Germany match the referee seemed to believe that football is a non contact sport. Schweinsteiger was booked for a perfectly fair tackle and Phillip Lahm had a free kick awarded against him for another. Germany were effectively forbidden from tackling to get the ball.
I hope England do not get that referee. If we do, Steve Gerrard will be back in the changing room almost before he has left it!
