The world number one has made history in the sport by winning 24 Grand Slam titles and pundit Mats Wilander hopes that he can inspire up-and-coming talent to reach the levels of competitiveness that he has managed.

The pundit told Eurosport: "I think one really important part of Novak Djokovic's future to me - and I think this is something that the coach must stress to him - is that the Novak Djokovic in today's men's game goes way beyond him winning 25 majors and being the best player in the world.

"I think tactically, Novak Djokovic is so much more mature and so much better than the young players coming up, and they're not going to ask each other those tactical questions."

Seven-time Grand Slam winner Wilander added: "I'm only looking at tennis hoping that it improves as a sport and the level becomes better and better. I'm not saying that's how Novak Djokovic is going to win more majors, but I think for the development of those younger players, he is playing a massively important part."

Djokovic has experienced a challenging start to the year with a rare loss at the Australian Open and the end of his partnership with coach Goran Ivanisevic and Wilander thinks he should let compatriot Nenad Zimonjic join his team.

He said: "Speaking the same language to me is massively important when you get a little bit older so that the coach can fit in, not just in Novak's mind, but also within his family, with his kids, and that becomes part of the family, so to speak.

"This is not a relationship that's going to last 15 years. We're talking about maybe 2-5 years. I think that to try and fit in a new person that speaks a different language is going to take too long.

"I don't even care or I don't think it's important if that player is older or younger even than Novak Djokovic. I think he has his team in place and he just needs some fresh ideas."
