Djokovic gets pep talk - from 4-year-old son

Melbourne - Fans across the world tuned in to see Novak Djokovic set up a 2019 Australian Open final against Rafael Nadal with a straight-sets win over Lucas Pouille.

His son was not among them.

Four-year-old Stefan was busy with other things, although he took time to give his old man a pep talk.

"No, my son is not watching me. He's going to pre-school," the six-time Australian Open champion said in his on-court interview.

"I actually talked with him 45 minutes before the match. He was telling me about Spider-Man. About, he was acting as a fish in an aquarium.

"He just tells me good luck - and make sure you win."

Djokovic's wife, Jelena, and two children didn't make the trip to Melbourne Park, but he's in regular contact.

"To be a father, there's no better thing that happened in my life," he said.

"With my wife, we've been together 15 years, now we're the parents of two angels. For me, this is life."

"Make sure you win." ??@DjokerNole's four-year-old son Stefan's advice to his dad before he takes to the court. #AusOpen pic.twitter.com/3gcMMezu5S
