"Djokovic will enter immortality if he wins Calendar Grand Slam" says Ivanisevic

The Calendar Grand Slam was last achieved by Rod Laver in 1969 just as the Open Era began. Doing so now is much hard to do due to the fact that the sport is that much more competitive than it was 50 years ago. The coach of Novak Djokovic, Goran Ivanisevic understands that:

“I am part of a team that writes history. If Djokovic wins the US Open this year and collects all four Grand Slams in the same year, he enters immortality, the rank of Rod Laver."

Ivanisevic was also of the opinion that doing it now is much harder than before admitting:

“Although it is much harder to achieve such success in the 21st century than in Laver’s time.”

The Croatian former Wimbledon champion saw first-hand how hard Djokovic tried and he explained it was not easy for the Serbian. Ivanisevic also spoke about how that is the reason he is in this position despite nobody believing it several years ago:

It was not easy for him (Djokovic),” Ivanisevic continued. “Five or six years ago no one could have imagined that Novak would be in a position to make this historic feat.”
