I am not trying to defend Novak's tantrums, racquet smashing or bailing out on MD.
However, it appears that his statement "pressure is a privilege" (which is not even original) is taken out of context. The following quote is from a newspaper article.
"The top-ranked Serb was asked how he deals with the pressure of attempting to accomplish something that no man has done before in tennis: completing a Golden Slam. Pressure is a privilege, my friend,” Djokovic said in answer to a reporter's question after winning both of his matches at the Ariake Tennis Park on Wednesday, beating Alejandro Davidovich Fokina of Spain to reach the quarterfinals in singles then teaming with partner Nina Stojanovic for another victory in the opening round of mixed doubles.
“Without pressure there is no professional sport,” Djokovic added. “If you are aiming to be at the top of the game you better start learning how to deal with pressure and how to cope with those moments — on the court but also off the court."
Djokovic, who has already won the Australian Open, French Open and Wimbledon this year and needs the Tokyo Games title and the U.S. Open trophy to complete a Golden Slam, said he has learned to deal with all expectations.
“All that buzz and all that noise is the thing that, I can’t say I don’t see it or I don’t hear it, of course it’s there, but I’ve learned, I’ve developed the mechanism how to deal with it in such a way that it will not impose destruction to me. It will not wear me down,” Djokovic said. "I feel I have enough experience to know myself how to step on the court and play my best tennis.”
Djokovic struggled more with mental pressure at the start of his career when he wasn't winning as much as longtime rivals Roger Federer and Rafael Nadal. He won the Wimbledon title this month to match Federer and Nadal with his 20th Grand Slam.
“Of course. It’s normal,” Djokovic said. “No one is born with those abilities. Those abilities come with time.”
If in this context, he has said that, I don't see it as being wrong.
