Novak Djokovic was bothered by some commentary that suggested his injury was faked or not as serious as he made it out to be and he promised clarification on it.
His coach Goran Ivasenivic dropped a hint suggesting that his injury was more sinister than it was thought by claiming that 97 % of players would have withdrawn from the event. Djokovic stuck it out and weathered the storm managing to reach the final and then shine in the final as well. Comments about the injury being fake arose pretty early in the event and Djokovic was disappointed by it. He's still bothered by it and he promised clarification surrounding it:
“He said it exactly – 97 percent? These two weeks I was thinking whether
I should publish anything about the injury, and I told myself that I
will, I want to. I will go into more detail and publish some photos on social media
about everything we went through. I don’t want to sound pathetic; I won
the trophy. But two years ago, a similar thing happened, and people are
doubting (that injury) even today, they say all kinds of things, make
fun of it etc. I feel the need to show and prove certain things. Not so
much for those people, but for me – some comments bother me a little.
You will get to know everything in a few days time.”
Djokovic's injury forced him to use every available hour to recover an nurse it which is why he never practice during his 'off days':
“That fact speaks for itself, it says that the injury represented
something that I needed to address in a proper way, so that I could
recover for my next match. If it was just a small issue, then I would
practice, right? I have never experienced this situation before, to not
practice on off days since the start of the tournament. There are certain things
that I would have liked to work on in practice – at least half an hour,
some patterns for my next opponent for instance. I wanted to in the last
four or five days, but my team stopped me: they said ’no’ and I
accepted it“.”
