The Rooney, Carragher, and Rafael have no bearing on whether Balotelli should have been sent off last night, so it's completely illogical to bring them into this discussion. That is for elsewhere. The way I judge it is this. Some tackles are malicious, some are reckless, some are violent, some are mistimed. Equally, some are done with brute force, and some are cowardly. Balotelli is a coward. And last night was malicious, but in a cowardly way. It wasn't the same type of maliciousness as in a player clearly elbowing someone, nor was it reckless in the sense of a player leaving the ground with two feet. But it was, in it's particular context, malicious, because he did leave his foot in, and actually, when you watch the clip, you will see goes beyond just running his studs down the player, he actually at the end, moves his foot forward to put further pressure on Popov's thigh. He knew what he was doing. It was extremely cowardly. Unfortunately, he has fooled some of you lot too.
However, I agree, the referee was very poor overall.
