In an interview with Serbian newspaper Kurir, Novak Djokovic's father Srdjan criticizes Roger Federer and Rafael Nadal for being jealous of his son's success.
"Federer is perhaps still the best tennis player in history, but as a man he's the opposite," Srdjan Djokovic said. "He attacked Novak at the Davis Cup in Geneva (in 2006), he realized that he was his successor and was trying to disparage him in every way. Novak's success is an amazing thing and something that Federer cannot understand."
Srdjan said of Nadal: "He was his best friend while he was winning. When things changed, they were no longer friends. This is not sport."
Srdjan had nicer things to say about Andy Murray, whom Djokovic has known since they were juniors and who beat Novak in the 2012 U.S. Open final and the 2013 Wimbledon final. "I have never, not even for a second, felt jealousy from Andy's family. They cannot be best friends as they fight for the most important titles, and (a) lot of money, but they approach their rivalry in the correct way."
