Borussia Dortmund sporting director Michael Zorc has refused to rule out the prospect of Jurgen Klopp one day returning to the club.
Klopp will end his seven-year tenure with the club at the end of the season.
When asked if Klopp could potentially return to the Signal Iduna Park dugout one day, Zorc replied: "Why not?"
"Maybe not in the immediate future, but Jurgen's still a pretty young coach so why shouldn't he come back to Dortmund? There's nothing to say he won't."
