The Brazil international said, "The situation is still the same - I want to play for Chelsea, as I have told the president, the coach and the sporting director.
"I want to play there - I don't know what more I can do.
"Calderon said that if a good offer came in they would let me go. Chelsea have made a great effort to sign me."
When asked whether he would refuse to play for Schuster should a move to the Blues fail to materialise, Robinho said: "No. If Schuster wants to keep an unhappy player then the responsibility is his."
He added, "Since May I've been trying to renew my contract but they didn't want to because they were so sure they would sign Cristiano Ronaldo," he said.
"Now, because they haven't signed anyone, they won't let me go."
