The amount that he’s won, the head-to-heads, the Masters (titles), the year-end number ones, the weeks at number, all those stats. Novak has won more Australian Opens than I’ve won Slams for crying out loud, what do you do but laugh? I don’t know what to say to that,” he said.He went on to emphasize that all three of them revolutionized the sport of tennis, but Djokovic had a clear edge on paper, saying,“I’m such a traditionalist for the game itself. When I look at what people bring to the sport, he (Djokovic) has brought so much, unquestionably. But then you look at what Roger has brought to the sport – the elegance and the class and the way that he did it. And then Nadal, the intensity or the ballistic nature in the way he engaged with the game. All of these guys have broadened tennis. When it comes to on paper, I don’t think you can argue against what Novak has done.”Over the course of his career, Novak Djokovic has won 24 Grand Slam titles, the most of all-time. He has also been ranked No.1 in the world for a total of 428 weeks. The 38-year-old is currently in action at the US Open, where he will be looking to further his status as the most decorated tennis player in the history of the sport.
