Chris Evert believes Rafael Nadal is 'sounding weary' at Roland Garros despite his fine five-set win over Felix Auger-Aliassime.
Nadal is rarely taken to five sets at Roland Garros, but the Canadian had him in trouble on Court Philippe-Chatrier on Sunday.
Auger-Aliassime took the first and fourth sets, forcing Nadal to go all the way before securing his spot in the quarterfinals.
There, he will face his old foe Novak Djokovic for a night-session showdown to reach the last four.
Evert, though, thinks the recent injury problems Nadal has suffered may have started to take their toll on him mentally.
“He is sounding weary," Evert told Eurosport after Nadal's win over Auger-Aliassime.
"There is so much more that comes with being a professional tennis player than playing a match, but he sounded tired.
“The respect I have for him because he is 35-years-old and he can keep getting psyched up every single day for these matches. I started burning out in my early 30s.
"When I woke up in the morning I didn’t have anything in me, so I don’t know where he gets this passion and fire in his belly from.
“I am sure with the injury, I don’t want to say he is falling apart, but you get a little more affected by the playing and training.
“It is going to happen, whether it is next year, two years, three years. I would not give him more than two or three years to play tennis.”
Rafael Nadal will face Carlos Alcaraz or Alexander Zverev in the last four if he is able to battle past Novak Djokovic.
