Epic 'small man' syndrome from the ref. Cant control the game on his own merit so he has to throw cards around.
That game was actually alright, but as soon as the players figured out that all they had to do was pretend to get hit and the ref would not only give them the ball but card the opposition it turned into amateur night.
He was carding people for clean tackles!
Either way, it sucks for Germany, but it isnt the end of the world, a win against Ghana and this means nothing, but it does put the pressure on them.
At the end of the day it was 10 man Germany against 12 man Serbia, they couldnt win, especially not when one of the Serbian players was carrying a whistle.
