Christian Pulisic scored his first senior team goal for Dortmund as Thomas Tuchel's team rebounded to beat Hamburg 3-0 just days after a devastating Europa League collapse against Liverpool.
Dortmund won going away as Tuchel started a team with eight changes from the XI that let Liverpool storm back to beat them 5-4 on aggregate and knock the club out of the Europa League.
Tuchel said he didn't believe that the Liverpool meltdown was still on his team's mind, while adding that he was impressed with the team's ability to forget about the loss and focus on the weekend task at hand.
"I do not think that Liverpool was still in our minds," Tuchel told Sky after the match. "I found it rather positive that we were able to concentrate on a task again.
"We had a lot of changes in the starting lineup. We had to find the positions and the pass rhythm.
"Hamburg's defending was aggressive and toxic. It just felt a little tough, but it's also not a crime.
"We have won 3-0 and are very satisfied. We are confident for the DFB cup match in Berlin. We want to reach the final."
Dortmund's win closes the gap to Bundesliga leaders Bayern Munich to seven points. They face Hertha Berlin in a DFB-Pokal semifinal on Wednesday.
