Diego Schwartzman was asked how he would describe the Spaniard Rafael Nadal after the US Open quarter-finals earlier this year.
The Argentinean said: "Like a lion in the middle, you know, in the jungle, you know. He's a fighter. He knows how to play the important moments every single time. I played eight times, and every important moment he played better than me (smiling). I don't know what to say, but, yeah, I agree with Matteo, for sure."
