Is there anything that Novak Djokovic cannot do? When he is not playing tennis tournaments, then be rest assured the Serbian tennis star is utilizing his time to learn a new skill.
In the past, Djokovic has been a keen learner of languages in whichever country he visited, as evidenced by his sharp grasp of basic Mandarin while globetrotting to play tournaments in China.
He also possesses the athleticism and a mental focus to excel in many other sports beyond his scope with his most recent cameo at the Ryder Cup springing to mind.
On Tuesday, Djokovic decided to attend Stjepan Hauser's concert in his home city Belgrade. Hauser is a Croatian cellist who has performed in more than 40 countries. Any other big-name celebrity would have probably whipped out their phone and unrestrainedly taken photos to be shared on social media.
Not Djokovic, who swapped his position from being a mere spectator to saxophone apprentice as the crowd chanted in unison prompting him to play it. The 24-time Grand Slam champion gave the crowd inside Belgrade Stark Arena their wish and blew into the saxophone, and could be seen laughing it off when he returned to take his seat.
Djokovic is currently completing the final few days of his break from tennis after winning the US Open and steering Serbia into the Davis Cup Final 8. He is preparing to return to the Paris Masters which will officially start next Monday, and he will be gunning for a record-extending seventh title.
Djokovic is in a tight battle with Spain's Carlos Alcaraz in the race to finish as the ATP's year-end No. 1 this season. Just 500 points separate the world's top two, with the Serbian man in prime position to reclaim that accolade from Alcaraz who won it last year. But if any slips in Paris and the ATP Finals in Turin happen, the Alcaraz will look to pounce.
