The Hoffenlander, led by defender Lars-Goran Eriksson, dominated the game.
It was a performance reminiscent of a typical game at the club, with both sides looking comfortable and in control.
“We knew the other team was stronger than us,” said Leverkusend coach Lars Rieding.
“I was really impressed with the effort that we showed.”
The Hoffenlagers first goal came after only eight minutes when substitute Rolfe Kjaergaard fired over after a cross from left-back Kjaerta Bierhoff.
Erikssen converted from the penalty spot to complete the comeback.
“It’s a good first goal for us, but I think we’ll have to work on it in the second half,” said Kjaercald, who was substituted on 56 minutes.
“The first goal was good, but we didn’t score a lot of goals.
We have to improve.”
Leverkusend’s second goal came 10 minutes later when Erikson converted after a free-kick from Kjaerdai Bierhof.
It looked like it would be the last for the home side but Leverkusdewa’s keeper made the best of a difficult situation.
“Our goalkeeper was really good.
I think he saved a couple of important chances,” said Riedings.
“And we were able to do that with our goalkeeper.”
Eriksson has scored six goals and assisted four for Leverkusene in the league this season, but the German will be wary of the German champions’ dominance.
“We know we have to win the game, but it’s a difficult task because the opponents have been very strong so far,” said Eriksen.
“They’re a good team, but they can be a very good team if they want to be.”
