Rafael Nadal HATES one French Open tactic - Diego Schwartzman advised of key weakness

Nadal is set to take on Diego Schwartzman in the French Open quarter-final this afternoon.

The world No 1 has yet to drop a set at Roland Garros this term and he looks on course to win his 11th clay Grand Slam.

However, Bartoli thinks if Schwartzman tries to play extremely aggressively then he could stand a chance of pulling off a shock upset.

Not many tennis supporters are backing the world No 12 but he has been given a glimmer of hope by the Wimbledon champion.

“Rafa doesn’t like to be rushed and if Schwartzman does that constantly then he might have a slight chance of pushing him, or at least taking him to a tie-breaker,” Bartoli told ITV.

Bartoli also suggested that the Argentine should take some inspiration from Maximilian Marterer, who caused Nadal some problems in the previous round.

“First of all he has to believe that he can do something,” she added.

“We saw it during Marterer against Rafa.

“Marterer was hitting a very heavy ball and taking a lot of risks and that is what you have got to do beat Nadal - or at least cause him a lot of trouble.

“The way Dominic Thiem played in Madrid, he was able to beat Rafa because he was pressuring him constantly.

“He was serving really well and hitting a fast and heavy ball.

“I’m not sure if Diego can serve as well as Dominic Thiem but from the back of the court he can hit a good ball.”
