Borussia Dortmund manager Jurgen Klopp has said that it was the "wrong day" for his team to face Liverpool following their heavy defeat at Anfield.

The German outfit were beaten 4-0 by the Reds in their pre-season friendly, and Klopp has admitted that he was disappointed by the defensive performance from his team.

"It was the wrong day and the wrong opponent for us in Liverpool," he told Ruhr Nachrichten. "The first two goals we conceded, we didn't defend well. If you make mistakes like those we made, then you will lose against an opponent like Liverpool.

"Our preparation has thus far been relatively unproblematic. From now on we will rest for the DFL-Supercup. The rhythm will come, then the freshness will return too."

Dortmund will face Bayer Leverkusen in their first Bundesliga match of the season on August 23.
