French federation president Bernard Giudicelli has hit out at the country's male players after their disappointing run at Roland Garros, saying they lacked physical strength and grit.
No Frenchman has gone past the fourth round at the Roland Garros this year.
"What the Frenchmen lacked to go further, it's grit," Giudicelli told French radio RMC.
"When a coach says that the player can spend eight hours on court when the temperature is 45 degrees Celsius and that he gets cramps in the fourth set, there's a problem," said Giudicelli, referring to Lucas Pouille who lost against Spain's Albert Ramos-Vinolas 6-2, 3-6, 5-7, 6-2, 6-1 in the third round.z
"Enough talking. We need to work according to the norms of modern tennis. It means having physical abilities very early and also work on the mental."
No French man has won a grand slam title since Yannick Noah lifted the French Open in 1983, something the so-called golden generation should have achieved, according to seven-time grand slam champion Mats Wilander.
"It is disappointing, for sure," Wilander, who is at Roland Garros commentating for Europsport, told Reuters last week.
"If you look at those guys, (Jo-Wilfried) Tsonga, (Richard) Gasquet, (Gael) Monfils... look at their rankings... for no-one to get to the quarter-finals is really quite disappointing.
"I think they have underperformed, really. And then who is coming next? Lucas Pouille, okay... but right now this kind of golden generation has not got much more time. This group is not going to be around forever.
"You would have expected them to have maybe won a grand slam by now."
The women have, however, fared better in Paris this year. Kristina Mladenovic and Caroline Garcia were both defeated in the quarter-finals -- the first time France had two women in the last eight since 1994.
"If the women have succeeded, it's not by chance. They took another path because we discussed, we questioned some things," said Giudicelli.
