Another humorous post was made on by Stefanos Tsitsipas on his social media that shows him eating bread with caviar and listening to the Russian national anthem, thus trying to answer the question he utters in the video:
"Tell me that you're Russian without telling me that you're Russian."
The post has already provoked a lot of comments from his followers: Some tell him that he then has to drink a bottle of vodka and play Balalaika, the Russian stringed musical instrument.
Others point out that the Russians eat only black caviar, except for Putin and his government.
However, it is not the first time that the Greek tennis player mentions Russia, especially as his grandfather came from Russia.
Last September there was a football match in his honour and Stefanos Tsitsipas made a post on twitter speaking fluent Russian.
