Axel Witsel admitted the 5-2 scoreline disguised the problems Hertha Berlin caused Borussia Dortmund during the first half at the Olympiastadion.
Hertha led 1-0 at the break thanks to Matheus Cunha’s 33rd-minute opener.
However, inspired by a sensational four-goal haul from Erling Haaland, Dortmund produced a stunning second-half display to claim victory in the capital.
“The first half was not our best half,” Witsel said.
“It was a little bit too complicated, and we gave away ball possession too easily.
“We did well to get back into the game in the second half and in the end we deserved to win.”
Commenting on Haaland’s impact, the Belgium midfielder praised the striker for his ability to turn things around in-game.
“Erling has incredible instincts,” Witsel said.
“Sometimes we don’t see him on the pitch for 30 minutes, but then he appears and scores lots of goals from a few chances. He did that again today and scored four goals.”
The win moved BVB to within one point of Bundesliga leaders Bayern Munich.
