Found myself thinking better without until Jelavic gave him a bit of a renaissance. Even then, he hasn't recaptured his best form. That miss against Norwich still grates, because I think we would have won with a 2-0 cushion. Still, he's a hero to me and it's hard to say we're better without him.
Honestly though, if we can get in Pienaar full-time, I'd play him behind Jelavic and Gueye on the left next season. If not, Osman, based on form. So, Cahill... bench player from now on. Sad as it is to say.
