The first-leg of the tie, played in Spain, saw Dortmund held to a goalless draw by Malaga.
With Die Borussen's failure to score an away goal, Malaga head into the second-leg with a slight advantage, although Dortmund manager Jurgen Klopp has since laughed off suggestions that his side are underdogs.
Nonetheless, many are still expecting Dortmund to progress past a Malaga side struggling in the La Liga, but Demichelis claims his side are more than capable of going toe to toe with Klopp's men when they meet again on Tuesday.
"It is quite possible that this will not be over after 90 minutes," Demichelis was quoted as saying by the official Champions League website.
"It might play into our hands but there is no way we will play for 0-0; it does not correspond with our philosophy.
"We will try to create chances, attack over and over. It will be important to show the qualities which have made us so strong in the past: intensity, aggression, intelligence.
"If we can bring all those qualities to life, we can be on a par with BVB."
However, Demichelis acknowledged Dortmund were chock full of talented players and warned his side to be wary of their counter-attacks.
"You can see a clear philosophy with Dortmund," Demichelis added.
"Almost every mistake is punished, because they attack so quickly.
"They run a lot and play dangerous high-tempo precision football. They are incredibly dangerous.
"We would be well served keeping them far away from our goal."
Pellegrini, who missed the pre-match post conference following the death of his father, is expected to return from Chile to take his place on the touchlines.
