He is very beatable in best of 3. I don't think he even cares about masters events. I expect him to lose very soon, maybe even his next event. When he goes down in best of 3, he always throws in the towel. It's not good for his reputation, but I don't think he cares. He only wants the majors.
Djoker's performance in the final was a disappointment for me. Didn't see Sparta Djokovic. For example I think even in this form Wawrinka would probably beat him 3-1, relatively easy.
I am not sure why he doesn't realize that he needs a bit more strength. Like not much, just add freaking 2-4 kg of muscle, it would do miracles for him.
