NOVAK DJOKOVIC joined in with a group of young kids to play tennis on the streets of Belgrade.
The Serbian star, 32, was back in his hometown for an event with his foundation alongside wife Jelena where they sang and performed on stage together.
But when he spotted a few youngsters enjoying a hit outside after dark, their hero stopped and joined in.
Djokovic, who also has a tennis academy in the Serbian capital, reportedly said: “It was spontaneous, I was coming back with rackets, the first time I saw the kids playing tennis without a net and then I told them I was going to bring a net between two lamp posts to hook them up and play nicely.
“It was great, for such moments one lives. Now, as a father, I invoke these situations to play with the children, and it is my pleasure to see the children play tennis, hit the wall, that’s how we all started.”
And unsurprisingly fans couldn’t get enough of the act of generous humility.
One said: “That’s why we love him! Not for his trophies and records only, but for this, him being a beautiful human being!”
Another wrote: “A simple, down to earth guy who loves his countrymen very much. No ego and all the humility in the world. Such a beautiful person. Wish all sports stars were like him.”
A third added: “Man of the people!”
A further user tweeted: “These kids will remember this forever. Bet they were buzzing afterwards. Absolutely love Nole.”
And Bear Grylls replied: “Love this.”
Djokovic lived through the NATO bombing of Yugoslavia as a child in Belgrade and developed into a talented tennis prodigy.
Now he is hunting down Roger Federer’s record total of 20 Grand Slam titles and the Greatest Of All Time tag.
He won his eighth Australian Open crown – and 17th overall – in Melbourne in January, beating Dominic Thiem in an epic final.
Djokovic reclaimed his world No1 status from Rafael Nadal in the process but was involved in a spat with fans and the umpire during the final, telling the crowd to “shut the f*** up” at one stage as his temper boiled.
But the star showed his compassionate side again on the streets he grew up on with his heartwarming selfless act.
