Chelsea boss Thomas Tuchel is unsure of Toni Rudiger's plans.

The defender is off contract in June.

Tuchel said, "I cannot predict the future.

"I don't know if he representative have talked to other clubs. If you know so or assume so, fair enough.

"It's January now and he has not signed yet but as I understand it, we are in communication with him.

"I assume he is very aware of what I demand from him and how I appreciate to work with him. The level in which he is playing is still super high and outstanding and there are no doubts that the situation is concerning.

"The club is trying the very best and the communication is still going on."
