Novak Djokovic plays down retirement talk, plans to play well into his 40s

"He has put a lot of hours and a lot of time into self-care, into recovery, into making sure that in a way every aspect of his body and mind is covered so that he can have a long-lasting, successful career. I know him personally and I learned a lot from him, from his example, and hopefully I can have a career that goes up to 40 or maybe even beyond - let's see."

Brady was in Djokovic's box at Roland Garros in June to watch his friend win the French Open, one of three Grand Slam trophies the Serbian captured in 2023 along with the Australian and U.S. Open titles.

"I feel great in my own body right now and I've been playing some really high-quality tennis," Djokovic added.

"2023 was one of the best seasons I've had in my life and why stop while you're still playing great? So I'll keep going and take (each) year, one by one, and see how far I go."

Alcaraz beat the Serbian in a five-set thriller to win this year's other Grand Slam title at Wimbledon and Djokovic welcomed the rise of the 20-year-old Spaniard, especially as Roger Federer has retired and Rafa Nadal is entering his last season.

"Our era is coming to an end, but you have Alcaraz emerging which is great, and I was very happy that I had four very good matches with him this year. Each match attracted a lot of attention, we had a lot of great highlights and it's good, it's good for our sport.," Djokovic said.

Djokovic will make his final preparations for a tilt at an 11th Australian Open title by representing his country in the United Cup in Perth and Sydney in the first week of the new year.
