Berlin, Germany: Peter Bosz took responsibility for Borussia Dortmund's latest failure with the Dutchman under intense pressure after home fans jeered his team who are 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.
Bosz took over as head coach 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," said Bosz.
"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 could be amongst Bosz's last as his position grows increasingly precarious.
Before kick-off, Bosz scotched rumours that the team influenced the starting line-up.
Bosz has three games left in 2017 to turn things around -- with Dortmund away to Mainz on Tuesday, home to Hoffenheim next Saturday and then at Bayern Munich in the German Cup third round on December 20.
"The coach can't do anything when we fire over the crossbar three metres in front of an empty goal," said Dortmund winger Andre Schuerrle 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 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 - that was really shit."
