Antonio Rudiger is keen to assess his options before making a decision over his future, but remaining at Chelsea beyond the end of this season remains a possibility.
Rudiger's contract expires at the end of the season and his representatives are not currently in talks with Chelsea over an extension.
Discussions between the parties did take place earlier this season but the defender is keeping his options open, with foreign clubs able to approach him from January onwards.
However, Rudiger remains committed to Chelsea and a decision to renew his deal at Stamford Bridge has not been ruled out.
Sky Sports News has been told that up to six of Europe's top clubs are ready to offer the 28-year-old a contract in January ahead of signing him on a free transfer when his Chelsea deal expires next summer.
SSN reported last month that the Blues will have to make Rudiger one of their highest-paid players if they are to stand a chance of keeping him at Stamford Bridge.
