Intro:

Rafael Nadal says he is fit but not sure if he is "ready to win" on his return to clay at next week's Rio Open in Brazil.

Script:

SOUNDBITE (English) Rafael Nadal:

"I'm feeling well physically that's the first answer. Then, I don't know if I'm ready to win here or not, on Tuesday starts the competition - the tournament starts from the first round, I never started not one tournament from the final so, I'm going to try to be ready for Tuesday to be competitive, enough competitive to have good chances. After that we will see what's going on - it's the first tournament on clay after a long time, you always need that period of time to adapt and matches are very important, so I'm going to try to be ready for Tuesday and then will see what's going on.

"The conditions (due to the hot weather) will be extreme, players are dangerous, players who are coming from Quito and Sao Paulo playing on clay already a few weeks. I did not, will be a big challenge for me and for me the first round will be tough, for sure, with any opponent. Will see what's going on."
