Hannover coach Dieter Hecking has quit the club after a meeting with club bosses.
Hecking has found himself under pressure since seeing his side lose to fourth-division opponents Eintracht Trier in the German Cup earlier this month.
There were calls for Hecking's head during last weekend's draw with Mainz and the 44-year-old has decided to resign from his post.
Hannover president Martin Kind confirmed Hecking's resignation and admitted he was sad to see the coach leave.
"This development hits me very hard personally," said Kind. "I have known and admired Dieter Hecking as a special person and coach.
"After a difficult season, we wanted to lead into a successful new beginning together, but this has not happened.
"Despite the difficult present situation, it has got to be said that Dieter Hecking and Hannover worked excellently together for year and were right for each other."
