Stefanos Tsitsipas, a firm favourite with tennis fans thanks to his witty personality, good looks and ever-evolving game on the court, has already been nicknamed Greek God and Greece Lightning – for obvious reasons. He’s currently ranked No 5 by the ATP and has already snagged eight ATP singles titles to date – a fantastic feat for a 23-year-old. His recent win – a back-to-back success at the Rolex Monte-Carlo Masters championship – proved to be a gruelling one, but the star kept his cool, maintained his grit and emerged victorious. It’s a meaningful victory for him as his mother, Julia Apostoli, won at the same event about 40 years ago. “[The] first time I walked in that club, in the Monte Carlo Country Club, with my mum, I think that was when I was six years old,” the Greek tennis star is quoted as saying on Tennis.com after his first Monte Carlo win last year. Why is Ash Barty giving up her tennis millions at age 25? Tsitsipas’ net worth stands at around US$20 million – largely thanks to prize money – and he earns an estimated salary of US$3 million from tennis and endorsements, as per Sportskeeda. According to the ATP, his career prize money amounts to just over US$18 million so far. He is backed by big-time brands such as Rolex (he was named the brand’s youngest ambassador in 2019), Adidas, Wilson, Rexona, Red Bull and more. In short, this tennis superstar is one to watch. Here’s what else you need to know about him. A family affair Tsitsipas has sporting prowess running in his veins. His father, Apostolos Tsitsipas, is famously known as his coach while his mother was a national tennis player in the former Soviet Union. According to Greek website Ellines.com, his aunt also once belonged to the same team as his mother and his grandfather, Sergei Salnikof, was a Soviet footballer. A love of the game has clearly carried over to the next generation, since Tsitsipas’ three younger siblings all play tennis too. “Stefanos started to play when he was really little,” Apostolos told Tennis World USA, adding that it was his son’s own decision to dedicate his life to tennis. “He woke up in the middle of the night and he told me, ‘Dad, I have to tell you something: I want to become a tennis player, I like the competition, I like the challenge.’” Coaching controversies Tsitsipas’ family follows his career closely and often travels with him to train and compete. While the support from family certainly gives Tsitsipas “extra strength” to play at his best, as his father told ATP Tour, it’s also been a source of controversy for the star player too. Tom Brady’s diet and wellness routine: 8 rules to staying healthy During last year’s US Open, Tsitsipas was called out by fellow players for taking longer-than-usual bathroom breaks. Former world No 1 Andy Murray pointed out on Sporting News how “a long break affects a player’s body” and German world No 3 Alexander Zverev suggested that he may be receiving coaching rather than just changing his clothes. Apostolos, who was also seen on his phone texting, only fuelled speculation that he may be coaching his son while he took his bathroom break. At the Australian Open this year, world No 2 Daniil Medvedev alleged that Tsitsipas was receiving on-court coaching from his father, and demanded that he get a code violation for it, Fox News reported. Defending himself against the accusations, Tsitsipas told the media: “I cannot hear anything when I’m playing.” He pointed out that his coach was “five kilometres away” and he finds it “funny” that he received a coaching violation. Rather than listening to coaching tips, he said he is rather focused on trying to read the game and find solutions while playing. Off-court charm Tsitsipas attracts plenty of attention off court too. The athlete vlogs regularly and, at the time of writing, his YouTube channel has almost 185,000 subscribers. Offering fans a glimpse into his daily life, he vlogs about his travels, hobbies and how he spent his days in quarantine. 7 ways the Beckham kids are following in their parents’ footsteps The tennis star is hands-on when it comes to producing content, creatively shooting and editing all the videos himself. On Twitter, he shows his quirky side, often revealing his most random thoughts. Case in point – on February 14, he wrote: “One minute you’re young and fun. And the next, you’re turning down the stereo in your car to see better.” In a Vogue interview last year, he also talked about his interest in graphic design (including creating his own font) and how he’s been into creating an identity through his fashion choices.
