Chelsea are yet to open contract talks with Antonio Rudiger.
The Germany international looked set to leave Stamford Bridge last year, only for moves to the likes of Tottenham and AC Milan failing to materialise.
However, since Thomas Tuchel's appointment at the start of the year he has become a regular for the Blues and played a key role in their Champions League triumph.
Rudiger's deal is about to enter it's final 12 months.
Sky Sports report that talks have yet to kick-off, with a number of clubs in England and Europe making their interest known.
