Novak Djokovic may still be going strong at 38, holding his own against the new generation led by Carlos Alcaraz and Jannik Sinner, but even he knows he can’t play forever. As the last active member of the legendary “Big Three,” every tournament he enters feels like a reminder that tennis is inching toward the end of an era.

Novak Djokovic has revealed his plans for after he retires from tennis, with the Serb's currently focused on winning a 25th Grand Slam title at the US Open. The 38-year-old has offered his clearest hint yet that his life in the sport will not end once he puts the racquet down.

Djokovic, 38, beat Tien, 6-1, 7-6, 6-2 to improve to 19-0 in US Open first-round matches, tying Roger Federer for first all-time. But he labored with low energy, a nasty blister on his right big toe and Tien’s level, especially in the second set.
