Ramos has been linked with a £40 million move to Stamford Bridge, but Calderon says: "Ramos' future is in Madrid.
"There is no need to be preoccupied. Sergio Ramos is one of the pillars of our project and his future is in front of him with Real Madrid. He could only leave if he wanted to, but I do not see any sign. He is happy with us.
"Who is happy at Real Madrid will want to move to another club?"
