Ekotto should've given away a pen as well. He pushed Pienaar so it was in no way a shoulder charge. Anywhere else on the pitch and it would've been a free kick.
Didn't Ekotto also charge blatently into somebody in the penalty area and get away with it a few months ago. The stupid commentators said it wasn't a penalty but he just steamed in with no intention to play the ball, don't even think he looked at the ball once
