The future of Peter Bosz as Borussia Dortmund coach hangs in the balance after the Bundesliga club called a press conference for later Sunday.
Dortmund did not confirm a Sport Bild report that Bosz would be fired but will give further details at the 1100 GMT conference.
The team lost to Werder Bremen on Saturday to extend their winless run in the Bundesliga to eight games and they have won just one of the last 13 in all competitions.
The 54-year-old Dutchman Bosz was appointed in summer as successor to Thomas Tuchel and initially started well at the club before the losing trend began.
