Djokovic is so fired up, you have to wonder if he sleeps at night
You mean like Federer. I think that he is well on the way. Witness his celebrations at the end of the match, before going forward to shake hands with Nadal.
I repeat here what I've said on at least one other thread. Having since my last post reflected on Djoko's increasingly outrageous behaviour, I'm thinking that he's now kept going by sheer adrenaline and will-power, i.e. he's living on the edge. Given that at RG he'll have to play three sets plus possibly 4 and 5 setters, I can see him going out, probably in the second week. The top has reached full spin now.
