What they’re saying

“I think Alcaraz has more arsenal than Sinner. Sinner is more like a robot that just kills the ball and does everything perfect. Carlos, he can do everything. He can do topspin, fire the ball, has good movement, goes to the net. It's more difficult to understand the game. He breaks a lot your rhythm.”

“I remember how I felt when I played Rafa Nadal for the first time in Madrid. These kind of matches will be important for him [Fonseca]. He has everything.”
