Did I mention a bit of drama too? Goran and I decided to stop working together a few days ago. Our on court chemistry had its ups and downs, but our friendship was always rock solid.”

Although Djokovic himself touched on the drama when he made his announcement, he confirmed that he was on good terms with Ivanisevic following their split. Speaking at the launch of Nikola Pilic’s documentary, the 36-year-old said: “First of all, Goran is my friend for life, mine and of my family’s.
