In an interview, Rafael Nadal's coach Francis Roig spoke about the next generation of players.
Asked who could go further, Roig replied: "Mental toughness comes from behind and you can only get to know the player when you are inside. This year Medvedev and Tsitsipas marked a difference. Tsitsipas was the one who evolved his game the most.
Before we were playing calm against him, this year he surprised me in Australia for his game style, he takes the ball much earlier."
