Bayern Munich coach Thomas Tuchel is seeking a reunion with Chelsea captain Cesar Azpilicueta.
The pair are close after winning the Champions League with Chelsea.
BILD says Bayern are now showing interest in Azpilicueta.
The 33-year-old has one year left on his contract and is seen at Bayern as an alternative to Manchester City defender Kyle Walker.
Azpilicueta is said to be available from Chelsea for around 8m.
