Sanchez has been our best player recently by a country mile. Why the fuck would you not start him... specially considering this is the last game before international break, and Sanchez usually comes back from those injured. Use him to the max when he is in such form.
It was the same in the last game, Sanchez on bench. Correa's injury got him into play and he won us the game. Inzaghi learnt nothing from that.
