In a world filled with high-stakes sports drama and superstar lifestyles, sometimes it’s the simplest acts of kindness that remind us what true greatness looks like.

This week, tennis legend Novak Djokovic shocked fans not with his performance on the court, but with a deeply personal gesture that has touched millions around the world.

While visiting his hometown of Belgrade, Serbia, during a brief break from the ATP tour, Djokovic decided to drop by his former elementary school — the same modest public school where he first picked up a tennis racket on the asphalt court behind the building. What he didn’t expect was to find a familiar face still there: Mr. Zoran Petrovic, the school janitor who had worked there for over five decades.

At 79 years old, Petrovic, affectionately called “Čika Zoran” (Uncle Zoran) by generations of students, was still faithfully sweeping hallways, fixing leaky pipes, and making sure the school grounds were clean — just as he had been doing since 1970.

“When I saw him, I couldn’t believe it,” Djokovic told reporters. “He was one of the first people who supported me as a kid. He always let me stay late to practice, even when it meant extra work for him.”

Moved by emotion, Djokovic embraced Mr. Zoran, who reportedly teared up upon seeing the now-world-famous athlete he once watched grow up. But the reunion didn’t end there.

In a private ceremony held at the school, Djokovic announced that he would be covering all of Mr. Zoran’s living expenses for the rest of his life, including medical care and a monthly pension, so the elderly janitor could finally retire in comfort.

“This man gave so much to us. He deserves to rest. He shouldn’t be mopping floors at almost 80 years old,” Djokovic said, holding back tears. “I owe him more than words can say.”

The moment was captured on video and quickly went viral, with fans praising Djokovic not just for his tennis accomplishments, but for his humility and humanity.

Local Serbian media reported that Mr. Zoran, a widower with no children, had continued working out of necessity, surviving on a modest public salary and refusing to ask for help.

“I never imagined Novak would remember me,” Mr. Zoran said in an interview. “He was a good boy—quiet, focused, always polite. I’m proud of him, but I’m even prouder of the man he has become.”

Tributes poured in on social media, with many calling Djokovic a “national treasure” and an example for younger athletes.

Even ATP President Andrea Gaudenzi commented on the event, saying:

“This is what real legacy looks like. Beyond trophies and rankings, Novak has shown us what it means to lead with compassion.”

Djokovic, currently ranked world number two, has long been known for his philanthropic work through the Novak Djokovic Foundation, which focuses on early childhood education in Serbia and beyond. But this act, so personal and so unexpected, has added a new layer to his public image.

“Sometimes we chase success and forget the people who helped us take our first steps,” Djokovic reflected. “Today reminded me that no victory means more than giving back.”

As Mr. Zoran begins his well-earned retirement, one thing is certain: this heartfelt moment between a tennis superstar and a humble janitor has won over hearts in every corner of the world.
