Madrid, PSG, Bayern and Juventus all have opened talks with the Germany international defender over a pre-contract agreement.
Chelsea boss Tuchel has said that he hopes that Rudiger stays at the club and has raved about him.
Tuchel told Sky Sports about Rudiger: “I cannot predict the future and I don’t know if his representatives are talking to other clubs or not.
“Of course, it is possible, it is January and he hasn’t signed a new contract with us yet but we are in communication with him, the club is in dialogue with his people.
“I assume he is very aware of what I demand from him and how much I appreciate him.
“The level on which he is playing is still super-high and outstanding, there are no doubts the situation is a concern for that. “My opinion is very clear, the club is trying their very best with him so the situation has not changed a lot.”
