De Marcos, 37, a year on from retirement, will focus on individual and collective development and help players adapt and connect with the first-team group.

German coach Geppert, 42, has been Terzic’s right-hand man, serving as his assistant during Terzic’s two seasons at Borussia Dortmund. He spent a decade at the club, including eight years in the academy.

Gaydarov, 35, arrives from Bayern Munich, where he coached the under-19s and led their Youth League side this season. He had six years at the Bavarian club after an earlier spell in youth development at Nurenberg.
