Borussia Dortmund manager Thomas Tuchel has expressed his disappointment at his side's 2-1 loss defeat atEintracht Frankfurt on Saturday.
Defeat sawDortmund drop to sixth in the Bundesliga, now nine points off league leadersRB Leipzig.
And Tuchel has criticised his players' poor performance and their lack of consistency so far this season.
"Technically, tactically, mentally, awareness -- everything. Our performance was deficient," Tuchel said at his post-match news conference - viaESPN.
"It was a performance, from the first to the last minute, that merited no points, starting from this week's training.
"Our entire season has been characterised by peaks and troughs. That is very unsatisfactory."
Dortmund conceded in under 20 seconds of kicking off in the second half,Szabolcs Huszti opening the scoring.
And, after Pierre Emerick-Aubameyang had equalised, they conceded again just 66 seconds later.
The lack of concentration is also an issue for Tuchel, who added:"I saw it coming.The manner in which we came out of the changing room -- I would have been surprised if we hadn't conceded a goal."
The defeat came after Dortmund had last weekend beaten rivals Bayern Munich in Der Klassiker to close the gap between the sides to three points.
Another setback has seen that gap restored to six points, however, with a title challenge now looking increasingly more unlikely.
Borussia Mönchengladbach are Dortmund's next opponents at the Westfalenstadion.
