Cilic lost to the best in the world (Djokovic) in the last 2 slams. Just terrible luck since Djokovic is his worst match-up. He would have gone really far if he got good draws. SF or even a final. I can see Cilic 2.0. beating anyone of the rest on a good day apart from Djokovic.
This means Cilic will meet Djokovic in USO final if he is in Nadal's half. Nadal should pray that he doesn't see this beast in his quarter/half. Otherwise he is toast.
