Borussia Dortmund manager Jurgen Klopp has blasted his players and questioned their commitment after a 1-0 defeat to Hertha Berlin left them languishing in 16th place in the Bundesliga.

The German accused his team of lacking determination and losing concentration when Julian Schieber scored the only goal of the game.

"We had too little determination in a game that meant so much," the BVB coach told reporters.

"The first half should not have happened because we played well in the game but we did not concentrate for the goal.

"This is completely the wrong way to go about things so we now have two more games until the winter break to dramatically improve our situation for the second half of the season."

Dortmund's latest defeat leaves them just one point off the foot of the table.
