What are Djokovic's problems, mental or physical? His childhood coach wants to know!

Jelena Gencic, tells the Serbian press that her former student isn’t admitting to certain things that are bothering him. No. 2 Djokovic was unable to win a medal at the London Olympics and hasn't won a title since Miami in late March.

"I never expected this result from him at the Olympics," she said. "Nole definitely has individual problems that he does not want to expose. I hope his team can understand what are the causes that prevent him from expressing his best tennis on the court and what has affected his level of play.  It's never easy to do the same thing each week, pack the suitcase and leave for a new place. A few days ago I read a newspaper the headline 'now I go to Toronto, after all '... What does ‘after all’ mean? I'm worried because he keeps saying he is tired. He must verify whether it is physical or mental fatigue."
