The 28-year-old Spaniard stormed to a ninth French Open triumph yesterday with a 3-6, 7-5, 6-2, 6-4 win over Novak Djokovic which also secured his 14th Grand Slam crown.
 
But he is not optimistic about collecting a 15th major when Wimbledon gets under way on June 23 despite having been champion on two occasions. His first title in 2008 was followed by a knee injury-enforced absence 12 months later.
     
In 2010, he was Wimbledon champion for a second time before finishing runner-up to Djokovic the following year.
     
Things then got steadily worse with a second round exit against Lukas Rosol in 2012 sparking a seven-month absence from the tour as his knee problems flared up again while, in 2013, he was dumped out in the first round by Belgian journeyman Steve Darcis.
     
That was the only time Nadal has ever exited a Grand Slam in the first round.
     
"I am going to Halle on Monday (for the grasscourt warm-up event in Germany). I want to try to play well at Wimbledon again," said Nadal.

"I am healthy, that's the most important thing. I hope my knee will have a positive feeling on grass because I felt my knee was better last year on the other surfaces,” he said.
     
"Grass is always a little bit harder for me after injury. I played Wimbledon in 2012 with my knee injury and I never played another match after. Last year I tried but I was not ready enough to compete,” he added.
     
"Let's see how are my feelings this year because it's a very important tournament," Nadal said.
     
After his loss to world number 135 Darcis last year, Nadal came under pressure to skip future grasscourt seasons if he wanted to prolong his career.
     
One of those urging him to rethink was three-time Wimbledon champion Boris Becker who has since gone on to join Djokovic's coaching set-up.

Nadal claims his ninth French Open

Nadal clinched his ninth French Open and 14th career Grand Slam title on Sunday with a brutal 3-6, 7-5, 6-2, 6-4 victory over a battling Novak Djokovic.

The world number one also became the first man to win five Roland Garros crowns in succession as the 28-year-old took his record at the tournament to 66 wins against just one defeat.
     
His tally of 14 majors equals the mark of Pete Sampras and puts him just three behind the all-time record of Roger Federer who is almost five years older.
     
Defeat was cruel for world number two Djokovic, the 2012 runner-up, who still needs a French Open title to become just the eighth man to complete the career Grand Slam.
     
The Serb dominated the early stages of Sunday's final, the pair's 42nd meeting, seemingly immune to the sweltering 30-degree heat on Philippe Chatrier court.
     
But Nadal, playing in his 20th Grand Slam final to Djokovic's 13th, grew stronger as the final wore on as he ended a four-match losing streak against his old rival.      

The 3hr 31min duel ended on a sour note when Djokovic double-faulted on match point, shaken by a shout from the crowd.
     
In a tense opening to their seventh Grand Slam final meeting, the steadier Djokovic, sporting a white cap against the fierce sun, pounced to break for 5-3, after Nadal put too much zip on a forehand.
     
The Spaniard had two points to break back in the ninth game but two more ballooned forehands kept Djokovic, who had even served and volleyed at 0-30, in the picture.
     
He took the opening set when Nadal, off balance and stranded behind the baseline, went long with a slapped backhand.
     
It was only the second time the champion had dropped the opening set of a final in Paris - in 2005 against Mariano Puerta and in 2006 against Roger Federer.
