Stuttgart have sacked head coach Tayfun Korkut after a run of just one win in seven matches at the start of the Bundesliga season.
A 3-1 loss to fellow strugglers Hannover on Saturday saw them drop to the foot of the table, with just five points to their name and a goal difference of minus seven.
The club have responded by dismissing Korkut and his two assistants, Ilija Aracic and Steven Cherundolo, despite him having signed a contract extension in June.
"The lack of development in the course of this season and the negative results have led us to take this step," said sporting director Michael Reschke.
