Rafael Nadal was seen on the tennis court with his son Rafa Jr., just days after Novak Djokovic enjoyed a hitting session with his son Stefan in Greece. Both tennis greats are now fathers of two children.Last week, a video circulating on social media showed the 38-year-old Serb hitting on court with his son Stefan in Greece. The lighthearted session was full of smiles and highlighted the 11-year-old’s growing passion for tennis, as well as the tennis legend’s hands-on approach to guiding him.Days later, 39-year-old Nadal was spotted on the court with his three-year-old son Junior. They were in the Rafa Nadal Academy, watching on as the Babolat Cup Masters Final unfolded in Mallorca. Junior was seen holding his racket in his right hand.Djokovic and his wife, Jelena, share two children. Their son, Stefan, was born in 2014, while their daughter, Tara, was born in 2017. The Serb often speaks about how both children keep him grounded and inspire him off the court.Nadal and his wife, Maria “Xisca” Perello, are also proud parents to two sons. Their first child, Rafael Nadal Jr., was born in October 2022. In August 2025, they welcomed their second son, Miquel, named in honour of Perello’s late father. Nadal retired from professional tennis in late 2024 and has since focused more on family life.Novak Djokovic's son Stefan cheered for Rafael Nadal at the 2022 Australian OpenNovak Djokovic's family at the 2025 Australian Open - Source: GettyNovak Djokovic did not defend his Australian Open title in 2022 as he could not participate due to the vaccination rules in Australia at the time. The controversy led to little to cheer for the Djokovic family, but his son Stefan still rooted for Rafael Nadal in Melbourne. "It was not easy for me to watch the Australian Open final. I was neutral; I did not want to cheer for any of the finalists because I badly wanted to be there myself. Still, my family got involved, as my wife cheered for Daniil, and my son for Rafa, jumping around after every point he won, fist-pumping as he does on the court," the Serb said (via Tennis World USA).Nadal faced Daniil Medvedev in the final of the 2022 Australian Open. The Spaniard was on his way to a straight-sets loss before pulling off one of the remarkable comebacks in Grand Slam history. He won 2-6, 6-7(5), 6-4, 6-4, 7-5.Djokovic returned to Melbourne a year later and grabbed his title back by defeating Stefanos Tsitsipas 6-3, 7-6(4), 7-6(5).
