Stefanos Tsitsipas may have attracted a legion of new followers for his on-court performances at the 2019 Australian Open, but the Greek star has also proven to be a favourite on social media.
And his channel has attracted the attention of American YouTube personality Casey Neistat, who has more than 10 million followers. Neistat has now called on the 20-year-old #NextGenATP player to collaborate with him, and Peter McKinnon, another popular YouTuber, after Tsitsipas leaves Australia.
Tsitsipas lost to 2009 champion Rafael Nadal on Thursday night in the Australian Open semi-finals.
