Cape Town - Goran Ivanisevic is predicting a stellar year for Novak Djokovic, but added he wouldn't even need it as he's already the best player in history.
Ivanisevic is a coach, close friend, and mentor of Djokovic, and he is adamant that the world number one has absolutely nothing left to prove.
However, he is currently third behind Roger Federer and Rafael Nadal in the Grand Slam title count, with Federer also above him in total weeks spent on top of the rankings.
None of that matters, though, says Ivanisevic, who believes it's just a matter of time before Djokovic holds those records too.
"I repeat, for me he is already the best tennis player in history," Ivanisevic told SK.
"When he is present, ready and healthy, there is no one better.
"What will be looked at at the end of their careers will be decided by people, but I think Novak will be the best in all relevant categories."
"I do not believe Novak will play for another five years, although he has a very good five years," he added.
"He will most likely top the Federer record for most weeks at No. 1 after the US Open and the record for most Grand Slams next year.
"He can even do that this year, for which he would have to win all three remaining Slams.
"But if he wins all three, then he has again done something that only Rod Laver has managed."
