Rafael Nadal has admitted that he is worried over his fitness for this summer's London Olympics.
The Spanish world number two is currently suffering with a knee problem following his shock exit to Lukas Rosol at Wimbledon.
"I am working as hard as I can and hopefully I will be at 100%," said the 26-year-old.
"I am the one who is most worried. I hope that things improve and my intention is to arrive in London well prepared and recuperated. It is for this that I work every day."
Nadal has been chosen to carry the Spanish flag during the opening ceremony of the Games.
