Christian Streich's men threw away a two-goal lead against Slovan Liberec on Thursday only to draw the game 2-2.
It was a result which fits in with the Black Forest club's general trend this season, but Streich hopes things will change this weekend.
"Of course we can do a few things better on Sunday," said Streich. "It's important that we start playing with stability again against this very settled and stable Berlin team, who play good football."
Freiburg have picked up just two points from their first five matches of the season and find themselves inside the bottom three with Streich's worst fears currently coming true.
Following an exodus of players this summer after finishing fifth last season, he predicted a fight for survival with European football presenting more of a hindrance than a blessing.
Opponents Berlin know exactly how justifiable Streich's fears are. In 2010, they were relegated to the second division a year after finishing fourth and only narrowly missing out on a place in the Champions League, just like Freiburg in May.
Facing Streich's men after their first European appointment of the season could therefore be an advantage, according to manager Jos Luhukay.
"We'll see how they cope physically and psychologically from their Europa League game," he said. "Freiburg don't necessarily seem very stable right now."
Former Freiburg midfielder Levan Kobiashvili could play a part for Hertha with Luhukay praising the 36-year-old, who spent six seasons in the Black Forest up until 2003.
"He's definitely deserved a place," said the Dutch coach, who will give Sebastian Langkamp a late fitness test.
Freiburg's new signing Vladimir Darida will have to wait a little longer before making his debut, meanwhile, with a knee injury still keeping him sidelined.
