The world number one claimed a record-breaking seventh ATP Finals win by beating Jannik Sinner in straight sets at the tournament in Turin and explained that he will only contemplate retirement if he is unable to compete with the likes of the Italian and Carlos Alcaraz.
Djokovic said: "[Holger] Rune, Alcaraz and him [Sinner] are, you know, the big three, the next big three, if you want to call them.
"They're going to carry this sport. I will hang on for as long as I feel like hanging on.
"As long as I'm able to still win against them on the big stage I'll still keep going because you know, why stop if you're still winning the biggest titles.
"But once they start to kick my butt, then I'll consider having a little break or maybe a permanent break from professional tennis."
Djokovic is aiming for more success in 2024 and says that claiming an elusive Olympic gold medal at Roland Garros in Paris is his big target for the year.
The Serbian ace said: "It is definitely one of the major goals for next year, other than Grand Slams.
"It's going to be a very congested schedule, going from the slowest to the fastest surface in the sport, back to the slowest. Clay, grass, clay and then hard courts.
"That's obviously a very demanding, challenging stretch of the year and I'm going to have to speak with my team to see how we can plan out our preparations, training, so that I'm able to play my best tennis where I want to."
