I don't think he played particularly great, but 90 minutes doesn't make someone Amauri. Last week he was making positive runs and getting into good areas (like today for the goal).
Just like last season, doesn't look that dangerous but keeps scoring in every game (should have scored last game too if his goal wasn't wrongly disallowed). He should be a starter.
So important that he finally broke his goalscoring duck, after a very frustrating match against Parma.
He could've had 3 goals by now. 1 wrongfully disallowed goal against Parma, and I think he would have scored on the chance that struck the post 9 out of 10 times.
What's great about this player is that he doesn't need many chances to score.
