Torres is a quality striker-best striker in the world when on form, just that I think injuries over the past seasons have hindered him.
If he never does find his form, it would be a mystery how a player can get from being world-class to well, what he is now. His lacking confidence and alot more, I reckon with a good pre-season behind him, Chelsea fan's should see at least some glimpses of the player that once was loved by the KOP. However he has lost pace due to all those knee injuries, that was the main way he got past players, so he'll have to find something new in order to bring him back.
