Djokovic annoys Nadal, Federer: Zagar

Speaking to Spanish newspaper AS, Zdenko Zagar said he was worried when Djokovic announced he had coronavirus.

But went on to claim the World No.1 was “better” than his critics and that they look to insult him because he is from Serbia.

"Now I know why he is constantly criticised," he told AS.

"They are dirty thoughts. The only reason I can think of to criticise him is for being Serbian, when many do not know where Serbia and Belgrade are.

“He is better and more famous than everyone who insults him."

Zagar went on to claim Federer and Nadal are ‘annoyed’ by Djokovic because he is World No.1

"Everything is explained because Djokovic annoys Nadal, Federer and the other 20 who are below him. I'm not going to comment on it. I should ignore them," Zagar added.

Both Federer and Nadal have remained silent over the Adria Tour event fallout.

Djokovic is is reportedly set to take part in the US Open, but is after confirmation around quarantine back in Europe before he commits.
