Borussia Dortmund coach Jurgen Klopp has backed his defence to take it up a notch after their recent poor performances in the Bundesliga.
The German champions travel to England to take on Manchester City on Wednesday, and the trainer has called for improvement as BVB aim to defend their league title and make an impact in the Champions League.
