Leicester City goalkeeper Ron-Robert Zieler is open to returning to Germany this summer.
The Germany international is frustrated after a season on the bench playing second fiddle to Kasper Schmeichel.
BILD says Stuttgart are interested in Zieler and contact has been made with the player's representatives.
Zieler has welcomed the approach and is eager to push through the move.
However, the Foxes are reluctant while Schmeichel's future remains undecided.
