Chelsea manager Thomas Tuchel says he has "trust" that the club and Antonio Rudiger will agree a new contract for the defender.
Rudiger, 28, is out of contract at the end of the season and has been linked with a number of European clubs.
He can now speak to other clubs as he is in the final six months of his deal.
"It's in good hands because I trust the club 100% and have trust in my player, so it's a no problem situation for me," said Tuchel.
"He's a guy who needs to trust you, he needs to feel the connection, he needs to feel the trust and he wants to feel it by minutes and actions.
