Calderon is adamant his club have no case to answer.

He said: "They don't have any evidence because nothing has happened.

"All there is is what the papers say and rumours that the player seems to want to leave. But at the moment a move is impossible because United don't want to sell him.

"It's United's right (to complain) but we haven't done anything and we are not going to do anything. It's a matter between the player and his club."
