At least some areas of his play has gone up despite the goalscoring not being a coherrent factor of his play lately. Last time i checked, he had about 15 assists to his name which is quite sublime for a striker - but, like everyone has said numerously, it is all about the goals. Hopefully a surge can hame more goals before the end of the season, as well as more assists, and help us turn around this season even more. I think he is gonna stay another season, which i think might be either his 'true' season under Roberto, or his 'closing' season, where his Chelsea career is finally given all hope from.
