Last season’s Champions League runners-up look set to progress to the quarter-finals of the tournament as they head into the second leg of their clash with Zenit Saint Petersburg at Signal Iduna Park on Wednesday with a 4-2 lead.
But Klopp says his side have already reached their target for the competition this year having made it beyond the group stage and insists his team won’t set out to defend against their Russian opponents.
“We have reached our goal in the Champions League by getting out of the group,” Klopp told reporters.
“Everything coming now is a bonus.
“We now have some experience in Champions League knock-out games. We will not go all out on the attack, but we will not only defend.
“We noticed there are many Dortmund fans in St Petersburg. That surprised us, as they spoke Russian. It was also nice.”
The coach added that Marco Reus will not feature on Wednesday’s match as he is still out with a muscle strain.
Klopp continued: “Unfortunately, Reus could not participate in team training and will not be available on Wednesday."
Meanwhile, Dortmund defender Mats Hummels says his side must be wary of Zenit's talent going forward.
The stopper said: “We have to be vigilant as they have enormous quality, especially in attack. The first leg put us in a good position.”
