We'll agree to disagree about the Carra incident. As for Vidic's first yellow, I'd imagine it was a result of several previous fouls, 2 of which were worthy of yellows in their own right.
Come to think of it, Vidic could have been given a straight red for his 2nd. Kuyt was clean through on goal and seemingly nobody within 15 yards of him. I guess the distance between him and the goal saved Vidic from that though.
You are too polite Baz, just tell the horrible scruffy rats to choke on everything about todays game!
