It was bound to happen, sooner or later. At this point I am not sure Novak will ever back to his old-self, being focused and motivated. His post-US Open interviews are indicating tennis is no longer something important to him. I was expecting some flops after Roland Garros. But the way US Open "slipped" out of his hands despite lucky circumstances might affected him more than we think.
London won't tell much, and I really don't believe he'll be #1 at the end of the year. But Australia will show where he is heading to.
It is okay to have "leak" months and even a season. But only if he intends to come back strong, I'd approve. Otherwise.. don't know. I am not his big fan, but I believe many of them are pissed off with his attitude on the court right now.
This situation reminds me on Borg. He was great and suddenly lost all his motivation and eventually retired while he still could winning slams left and right. I do believe Novak still has at least two slams in his body, but obviously not in mind. Truly pity.
Well, after all, I am already into #netxgen bandwagon lol
