Diego Schwartzman’s coach Juan Ignacio Chela is backing his man to cause Rafael Nadal problems when they meet in the US Open quarter-finals.
Schwartzman delivered an impressive performance to knock Alexander Zverev out of the tournament in four sets.
But he now faces Nadal, who has played the best tennis so far in the tournament.
However, Chela is confident in Schwartzman’s ability to beat Nadal if he shows ‘fighting spirit’.
He told the ATP: “Diego’s playing at a very high level and I like his chances regardless of the opponent.
“We’ve had our chances against Rafa in the past, too, if not the wins.
“I want to see that fighting spirit. I want to see him being aggressive, moving into the court and using his legs, tracking down every shot and transitioning from defence to offence.
“Those are our keys to victory.”
Nadal and Schwartzman meet in the second night match of the day and the Spaniard says he is full of respect for the diminutive Argentine.
He said: “He is one of the most talented players on our tour. He has everything, amazing control, amazing speed.
“He has the ability to read very well your shots and to understand very well the game. Is not a surprise he is there.
“Before the match, I know people can think that [Alexander] Zverev was favored before that match. Honestly for me, today, Schwartzman was favoured.
“Schwartzman, I saw him play a couple of matches during this tournament, he was playing great.
“Sascha played two matches, two or three matches close. Physical issues always I think. The other arrived fresh and playing amazing.
“Even if he lost the first set when he was 2-0 and big chance for 3-0, double break, in the beginning, finally he lost the first set.
“After that he was playing amazing. Sascha fought hard as always. He going to be a Grand Slam champion soon I think.
“But today Diego is playing unbelievable. I need to play my best in the next round to have the chance to be in that semifinals. But the match of today I think helps.”
