Nadal: Rio Olympics my real goal

Rafael Nadal has already proved a lot of his doubters wrong the past year, but he wants to put the cherry on the cake by taking part in the Olympics in Brazil.

After missing the bulk of the 2012 season and the first half of the 2013 campaign due to his troublesome knee, many believed that he is unlikely to recapture the form he had earlier in his career as his physical style had taken its toll.

However, the Spaniard returned with new vigour and went on to win 10 titles, including the French and US Opens, and played what many considered to be his best tennis.

Nadal, though, is not done yet as he is aiming to take part in the 2016 Olympics in Rio.

"For the last five years, it seems like lot of people were saying I will not be able to play long the way that I play," said Nadal, won who won gold in the singles at the 2008 Beijing Games.

"But I am here again at 27-and-a-half years old and I really hope to have the chance to be here for a lot of more years.

"So still in my mind Olympics in Brazil. I really want to arrive there in good condition. It's a real goal for me."

Although his form has been irresistible since he made his comeback, Nadal admits he's not completely without pain when he is playing tennis, but at least it no longer restricts his movement.

"But the feeling on the knee is very good for me because even if I have pain a lot of days, the pain is not limiting my movements," he told AFP.

"That's the most important thing. I am playing with no limitations. I am free when I am playing.

"Even if I have pain, I am able to control that pain. In the past I was not able to control the pain, so I couldn't play. But the feeling is I would like to improve a little bit more."

Despite his success on the hardcourts of Flushing Meadows this year, Nadal still feels that the surface puts too much strain on the players' bodies.

"I say this because I think it's going to be better for the next generations, if they are able to play on an easier surface for the body, to try to have a longer career, to try to be more healthy when they finish their careers," he said.

"Probably I will not be that lucky."
