what? I didn't see this part. What did Djokovic do? Hide his food from the camera?
yes, under the towel.
Anyway, he was very honest in the interview on-court with Courier that his recovery in 4th set was related to "eating energetic things, liquids ..."
Murray also took some time drinking between points, probably Lendl's advice, but I don't remember seeing that before ?
As for the match, it was good but not that good imo : I was disappointed about Murray in 2nd and 3rd set : the way Djokovic was playing Murray should have gone advanced much quicker imo and it would have helped him much in the end.
