Stefanos Tsitsipas' YouTube channel is experiencing a surge in subscribers after he reached the Australian Open semi-finals and the Greek youngster will hope to add to his highlight reel when he faces world number two Rafa Nadal on Thursday.
In 2012 a shy young Greek tennis player was interviewed at the Kungens Kanna & Drottningens Pris tournament in Stockholm.
Clutching a microphone, 13-year old Stefanos Tsitsipas told an interviewer he had started playing at the age of three, his idol was Roger Federer and one day he wanted to make it to the top.
On Thursday night in Melbourne, 20-year-old Tsitsipas faces the might of Rafael Nadal in the Rod Laver Arena in the semi-finals of the Australian Open, having defeated Federer in the fourth round.
After overhauling Federer 6-7, 7-6, 7-5, 7-6 Tsitsipas won his quarter-final against Roberto Bautista Agut, also in four sets.
Stefanos Tsitsipas' YouTube channel is experiencing a surge in subscribers after he reached the Australian Open semi-finals and the Greek youngster will hope to add to his highlight reel when he faces world number two Rafa Nadal on Thursday. Tsitsipas, who offers insights into his career and travel on the channel, has seen his subscriber base soar to nearly 50,000 after his four-sets quarter-final victory over Spain's Roberto Bautista Agut on Tuesday.
"I started (making videos) last year, inspired by some other people. When I'm desperate, when I feel down, I do these videos, I actually feel better," Tsitsipas, who stunned holder Roger Federer in the fourth round, said.
"It makes me realize that tennis is not the most important thing in life, that we all have some other talents that we don't know about. It kind of makes me more relaxed."
Tsitsipas' relaxed outlook to life belies the determination that has helped the 20-year-old go from a bright prospect to a genuine contender for a maiden Grand Slam title at Melbourne.
It is one of the reasons Nadal will not take Tsitsipas lightly despite beating him in straight sets in their two previous meetings last year.
"When you face these young players, they are in permanent improvement. He's with confidence. He won a lot of good matches. (It) Will be a tough one," Nadal, who beat another young contender in Frances Tiafoe in the last round, said of Tsitsipas.
"For me, it's always the same: you're in the semi-finals of a Slam, you can't expect an easy opponent. Stefanos is one of the best players in the world. To have the chance to be in that final, I need to play my best."
