Novak Djokovic: the greatest tennis player of all time?

Djokovic effectively gatecrashed the Federer-Nadal duopoly, that dominated men’s tennis in the second half of the 2000s. His first Grand Slam title came at the 2008 Australian Open, but that was just a taster. Of the 42 Grand Slam events played between the 2011 Australian Open and Wimbledon in 2021, he won 19 of them. And he has topped the world rankings for much longer than anyone else – man or woman – in history.

To many, the pinnacle came in June 2016, when he not only completed his career Grand Slam by winning the French Open, but became the first man since Rod Laver in 1969 to hold all four major titles at the same time. Although his form dipped after that triumph due to a mixture of injuries and off-court issues, he bounced back impressively to win eight more majors in 2018-21, return to the top of the rankings, and fall just one match short of emulating Laver’s calendar year Grand Slam when he lost in the US Open final of 2021 having won in Melbourne, Paris and London.

The numbers continued to get better. His victory at the 2023 US Open gave him a 24th major title, equalling Margaret Court’s all-time record set in an era of much less intense competition. It made Djokovic the first man to win three majors in a calendar year four times.

And even in 2025, a year dominated by the young Carlos Alcaraz and HEAD tennis ambassador Jannik Sinner, Djokovic still made it to the semi-finals of all four majors, three of them after his 38th birthday.

Teaching him tennis – and how to handle greatness

Djokovic is a complex but positive character. The product of modest surroundings, he was a child with immense curiosity, a work ethic to match, and a belief in his own ability that included going onto a Serbian children’s TV programme at age seven to say with a totally straight face – and a cap facing backwards – that he was going to win Wimbledon.

The person who most shaped him was Jelena Gencic. A tennis coach from a highly educated family who had never had children of her own, she was conducting a tennis clinic in the mountain resort of Kopaonik, where the Djokovic family had a pizza restaurant, when a six-year-old put his face to the fence and watched for an entire morning. When she approached him in the lunch break, it was clear he was interested, so she invited him to join. That afternoon, Djokovic’s tennis career began.

Gencic, who died during Roland-Garros in 2013 (the news was kept from Djokovic until after his third round match), claimed she saw his talent from day one. She told his parents they had “a golden child”; they were happy to believe her and let her coach their son. She remained his formal coach until he was 12 and needed a more international coaching framework.

But Gencic did more than just coach Djokovic. She says she recognised that he was destined for greatness, and felt part of her job was to prepare him for that. She encouraged him to listen to classical music, to read poetry, to take an interest in scientific discoveries and philosophical arguments.

He refers to her even today as his “tennis mother”, but she was more than that – she helped shape the mind that is open to many unique and interesting ideas.

HEAD since junior days, now a Speed Legend

There has always been a strong philanthropic side to him. He has a foundation that not only gives money to a number of charitable causes, but also sets up programmes to help with education and skills training to create opportunities for disadvantaged youngsters in Serbia.

Although seen as something of an on-court warrior and flag carrier for Serbia – whose modern-day sovereignty is still only 30 years old – Djokovic has a benevolent temper and a willingness to see the good in people. He is a practising Christian who believes in being a good citizen, and above all a good father to his two children, Stefan and Tara.

There is a common myth on the tennis tour that Djokovic only switched to playing with HEAD rackets in early 2009, but he had played with HEAD in his junior days. He was then offered a lucrative contract by another racquet maker, but at the end of the 2008 season he wanted a racket with which he could conquer the world, so returned to HEAD.

All his 23 majors between 2011 and the end of 2023 were won with a HEAD racquet in his hand – making Djokovic and the SPEED racquet series endorsed by him one of the most successful partnerships of all time. HEAD commemorated it in 2023 by bringing out the Speed Legend for Djokovic, an all-black frame that is exclusive to Novak.

Novak Djokovic is more than just a tennis player – he is a statesman, both within tennis and representing Serbia on the international stage (the first biography of him was entitled ‘The Sporting Statesman’). He became president of the ATP Player Council in 2016, and in 2019 after three members resigned, he recruited Roger Federer and Rafael Nadal. It was the first time the world’s top three players had been on the Council, and Djokovic was both the president and the top-ranked player.

The march of time means the end of Djokovic’s career is much closer than the beginning, as he often admits. Even his remarkable fitness and match temperament are now barely a match for the Sinner-Alcaraz duopoly that leads the next generation. Yet in the most competitive period in the 150-year history of modern-day tennis, Novak Djokovic dominated the biggest tournaments and surpassed Federer’s total of 20 majors, Nadal’s and Steffi Graf’s 22, and Serena Williams’ 23. That’s why numerous experienced tennis watchers see this highly intelligent, worldly interested, and sympathetic man as the greatest tennis player of all time.
