What about that moment in the 2nd half when Wollscheid fouled Pelle just outside the box and while the ball went out to the right wing, he continued to hold him back, thus stopping him from getting a chance to be on the end of the cross.
If he was playing the advantage, rather than merely ignoring the foul, which he did for the rest of the game,why didn't he call play back and book him?
In a list of shyte refs he is in a medal position.
