But the 63-year-old has previously explained how he wishes that his son would retire from tennis this year. “I think for some time that he should have stopped working this extremely difficult job,” Srdjan said in a documentary last year.

“As far as my wishes for him go, he has already fulfilled them all seven/eight years ago. The rest is this amazing bonus.

“Tennis is only one segment of his life, not his whole life. I expect him to be recognised for the things he will do after his career ends as well, after he leaves the tennis world, which I hope it will happen next year. And for Novak to slowly but surely… it’s not the end, but in a year-and-a-half let’s say.

“My wish as a father – I think for some time that he should have stopped working this extremely difficult job. It’s physically and mentally challenging and very demanding – with him being fully dedicated for 30 years, and not taking his foot off the gas, there is not much time for other things in life.”
