Boris Becker and Srdjan Djokovic, the 16-time Grand Slam winner's father, once claimed Novak Djokovic and Roger Federer are false friends. The Serbian player clarified it's all good between him and the Swiss. "We have a very good relationship.
We respect each other. Ok, we are not friends, we do not have dinner together. We are colleagues, rivals. It's difficult to be friends when you compete on a court." Djokovic believes you cannot pick the greatest player ever for a simple reason: "You cannot compare tennis 50 years ago and now.
Laver, McEnroe, Connors, Lendl. They played with wooden rackets, it was a different kind of tennis: rhythm, whole Tour. Who knows how good would those players be now? Rafael Nadal became even more complete, he started playing an unbelievable tennis too."
