Djokovic called it 'malicious'; despite fellow Serbian Viktor Troicki, Bulgarian Grigor Dimitrov and Croatian Borna Coric all also testing positive.

“I can only see criticism lately and much of it is malicious,” Djokovic told Wednesday’s issue of Serbia’s daily Sportski Zurnal.

“It’s obviously more than just criticism; it’s like an agenda and a witch-hunt are on. Someone has to take the fall; a big name.

In terms of the US Open, he isn't sure if he will play in the Grand Slam yet: “I still haven’t decided whether I will play in the U.S. Open; the upsurge in registered COVID-19 cases in the United States and New York in particular are not playing into the event’s hands,” added Djokovic.

“My intention was pure; I was whole-heartedly committed to organising a humanitarian event; to help players and tennis federations in the (Balkan) region,” he said.

“We complied with all the laws and regulations. But we’ve learned our lessons; some things could have probably been done in a different way.”
