World number one Novak Djokovic has insisted that the successes of both Roger Federer and Rafael Nadal are the result of hard work from his fellow Wimbledon competitors.
Current SW19 champion Djokovic came through his first-round clash unscathed, while Federer and Nadal get their campaigns underway on Tuesday against Damir Dzumhur and Thomaz Bellucci respectively.
"Roger has always taken care of his body and the scheduling. Obviously technically, he's probably the best player in the world. When he plays, it looks so easy, it looks so flawless," said Djokovic, according to the Irish Examiner.
"I think the kind of game that he has, the proper care that he had about his body and professionalism has kept him so durable, kept him at the top of the men's game for so many years. He's still up there.
"And Rafa on the other side, he's somebody that spends a lot of hours on the court. He really loves to practise for two, three hours in a row. He is just somebody that has a hard working ethic. It really pays off."
Djokovic has achieved eight Grand Slam titles in his career so far.
