“About 15 years ago, Federer attacked my son when he was very young, only about 18, 19 years old,” Srdjan earlier this week told Serbia's K1 TV channel. “Federer is a great champion … But even if he is a great champion, he is not a good man.”
Srdjan continued the conversation by protesting “unbelievable” criticism against his son, calling Djokovic “the great champion that the world would never have”.

Srdjan repeatedly launched public criticisms against Federer, accusing him jealous of Novak Djokovic for his son's “divine” tennis.
In February, Djokovic also caused a conflict with Federer when he said that he was treated in unfairly by the world media compared to his opponent. According to Djokovic, the world media does not appreciate his victory over Taylor Fritz at the Australian Open as part of that “injustice”. At that time, Djokovic was said to have played a injury in the abdomen.
He mentioned the differences when the media praised Federer's victory over Tennys Sandgren at the expansion of the 2020. Federer at that time also suffered an injury in the groin area.
“To be honest, I almost got used to this. I couldn't say that it didn't affect me at a few times. Of course, the communication was injustice, unfairness that had an impact on me. I am also a human being, I have my own feelings and of course I don't like it.”
