Peter Bosz is on the verge of being sacked, according to reports, after Borussia Dortmunds latest failure left them winless in their last eight Bundesliga games.
Dortmund's miserable run continued on Saturday as they crashed to a 2-1 home defeat against third-bottom Werder Bremen.
Magazine Sport Bild report that the decision to fire Bosz as head coach has already been taken with an announcement due to be made on Sunday.
Bosz took over before the start of the season and got off to a great start as Dortmund led the league table by five points at the end of September.
But they have taken just three points from three draws in their eight league games since, dropping to seventh -- out of the European places for the first time this season -- following their latest defeat.
"The first half was like nothing I have seen since I arrived at Dortmund," Bosz said after the loss to Bremen.
"Obviously, the players have to do their work on the pitch, but I'm the one responsible and it was really bad today."
After exiting the Champions League at the group stage, the Bundesliga defeat at Dortmund's Signal Iduna Park appears to be the final straw after Bosz's position had grown increasingly precarious.
Before kick-off Bosz scotched rumours that the team influenced the starting line-up, while winger Andre Schuerrle admitted the Dutchman wasn't the only one at fault for the club's dramatic dip in form.
"The coach can't do anything when we fire over the crossbar three metres in front of an empty goal," Schuerrle said after midfielder Shinji Kagawa blasted over in the dying stages.
"At the moment, it's a question of mentality."
Bremen went ahead when Germany Under-21 midfielder Maximilian Eggestein rifled home unmarked from the edge of the area on 26 minutes.
The hosts got back on level terms on 57 minutes when Kagawa's headed cross was bundled in by Pierre-Emerick Aubameyang who was grappling with defender Philipp Bargfrede.
But Bremen restored their lead eight minutes later through a header from Czech defender Theodor Gebre Selassie.
Dortmund captain Marcel Schmelzer slammed the performance.
"That was impudent, it was crazy," fumed the defender. "For weeks, I have been saying that we have to stop talking and act.
"I don't understand how we can produce a performance like that."
