Novak Djokovic’s son, Stefan, has been a fun sight throughout Wimbledon as the boy joins the six-time champion on the practice court. But it may surprise people to know that young Stefan is developing a forehand much like Rafael Nadal, with a follow-through zipping over his head.

“He likes to do that. He likes to intimidate me on the court with finishing the swing here. He knows I don’t like that particularly. I’m trying to teach him to finish the hand here, the swing, over the shoulder. He does that, but he does this as well. Whenever he does that he always laughs because he knows. We have these kind of funny moments on the court,” Djokovic said.

Djokovic is making sure that he enjoys every moment that he shares with Stefan, on and off the court, as he pursues his 7th trophy at The Championships and his 21st major title.

“I try to use every available opportunity, possibility, time to play with him because he’s right now fully immersed into tennis. Everything around tennis, how he can play, he’s watching, he’s analysing. We’re talking. “[Saturday] night when I was putting him to bed, he was asking me questions: What is the difference between the racquet head sizes, the strings, why somebody is stringing less tension, all these basic questions that kids are very curious about,” Djokovic said.

“He’s in love with tennis right now. It was fully his own desire to really pursue tennis. So of course I’m going to be there for him. I never force him to be on the tennis court, but if he wants, I try to always make myself ready to be there and play with him.”

He said he will support Stefan “any possible way” if he is interested in going into professional tennis in the future. At the moment, the boy is still too young to think that far ahead about the matter.

Djokovic said, “It’s important for me that we have a relationship as a father and son, first of all, primary, before anything else, and that he’s enjoying life, that he’s having fun. He’s trying different sports. Super important. I was growing up with skiing, football, tennis, martial arts, different things. I feel like it’s very important to have, particularly at this young age, a lot of stimulus to the children from different perspectives and different sports and different movement, different activities.

“I don’t like children very early just doing only one sport. I feel like it’s important to try different things because it will help the development of the brain and also motor skills.”
