The BVB's trainer has moved to sweep away the recent criticism aimed at his read guard, stating that his back four will improve as the season progressesBorussia 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.
"We have we lost our sync in defence during the 14-week summer pause," he explained to Bild.
"However, we are like an orchestra. The Berlin Philharmonic do not start playing to the best of their abilities right from the start. It takes team practice. We can and must find our sync again."
Dortmund currently sit third in the Bundesliga table, seven points behind leaders Bayern Munich, and Klopp feels that his side have given their rivals a big advantage in the quest for silverware.
"We have done Bayern a big favour. They had two very good seasons but we were better both times. That has made them even more determined to make up for their heartbreaks."
"They have high quality. There is no team currently as keen to make up for their short comings as Bayern."
