Schuster claimed he had been kept in the dark over Real's pursuit of both Manchester United winger Cristiano Ronaldo and Hamburg's Rafael van der Vaart.
But Calderon countered: "I do not want to talk about some statements that I have not seen myself, but the coach knows perfectly well that he is the first to be informed. It's logical, since he is the one who coaches this team.
"I still maintain that I have full confidence in him, we all have and will remain so. Here, fortunately, there is no problem and we are happy that there are no problems."
Told that Schuster appeared angry in his media conference, Calderon replied: "I do not know his words, but I am convinced that these were made in an ironic tone or misunderstood. The atmosphere is wonderful."
