Tsitsipas is the real deal. I saw him court side in Sydney in January and chatted with him and some coaches during the week - I have his autograph and pics/videos I can post. Right then I predicted he’d beat Federer at AO If they met before the final. He’s the modern Borg. I predicted big slam totals for Sampras and Nadal before they won one, and Tsitsipas is the next big champ. Forget about Medvedev/Kyrgios.
