Simeone insists no transfer discussions have been held, with there a strong desire on his part to see Turan remain in the Spanish capital.
He said: "First, I have not heard anything and I have seen it a lot. Everyone can comment on whatever you want.
"The important thing is what he shows on the field. Arda is one of the best players. He shows heart in every one of our matches.
"He has a contract with our club and he shows everyone what he has to offer."
