I didn't find Hart shaky in the least. His only mistake was overcommitting on the Defoe goal: he came out too stiff. He could learn a thing or two on THAT part of goal-keeping from Pepe.
I am annoyed that Lescott did not get punished retroactively. If intent is irrelevant, then his stiff-arm was clearly 'violent conduct'. I don't think he intended to 'clock' anyone, but he was clearly using 'brutality'. Stiff-arming is not allowed in football (the real kind).
Dzeko could not possibly be compared, performance-wise to Savic. The latter was criminally naive, short of confidence, etc. Dzeko just had a quiet game. Between Dzeko and Balotelli, I fear the former much more, for he's a skilfull, intelligent player and not prone to theatrics and going for 'magic'.
