"This calendar I am playing with this surface — hard court surface — is tougher than grass or clay for the body, and all the time we are playing more on this surface," said Nadal.
"In my humble opinion, we have to change that a bit more," the Spaniard said. "I can say that because I won a grand slam on hard (courts)."
Nadal, 22, has previously won four Grand Slams on the French Open clay courts, as well as Wimbledon on grass last year.
"Before if I say that, a lot of people think 'He wants to change because he's a clay player.' But believe me, I don't think anything about if I am a clay court player or not.
"When I say this, I think about the best for the players and for the future. It's not possible to have a lot of injuries on tour like this. So we have to try to change something."
Many are saying he should put up with it like the rest, that he complains too much about the situation.
As for me, I think he deserves his say. What say you, Rafanatics?
