Stuttgart have confirmed the departure of head coach Hannes Wolf after their 2-0 home defeat to Schalke on Saturday.
Although Stuttgart beat Hertha Berlin 1-0 in their first match following the Bundesliga's mid-season break, Wolf's men subsequently suffered back-to-back losses.
And following talks in the aftermath of the Schalke loss, which left the club 15th in the table, Stuttgart announced the end of Wolf's tenure on Sunday.
Sporting director Michael Reschke said: "We firmly believe that the danger that the current situation cannot be turned around is too great and that we need a new impulse to get back onto a more successful track.
