Hertha's 1-1 home draw against Augsburg on Saturday saw the team stretch to four their winless streak, which included a 2-0 capital derby defeat by Union.

Dardai, 45, rejoined Hertha in January this year after having been sacked a first time in 2019.

German-born ex-midfielder Korkut, 47, signed a contract until the end of the season, not having graced the dug-out in the three years since he was dismissed as coach of Stuttgart.
