For a game with not a lot riding on it, at least for Man City, the 2nd half (which is all I saw) was feisty to say the least, with a feeling that the Swiss ref was not always in control. However, give Scharer his due, his decision to red card Walker for lunging at the back of an opponent's leg was spot on, and City must be ruing the decision to keep their key England defender on the pitch long after it became clear that he was losing his rag, and will now miss a key game at the KO stage. Not a good night for City and their management and not a particularly good 2nd half for the referee.
