Goals were all Gladbach lacked in their opening day 3-1 defeat to Bayern Munich and coach Lucien Favre has placed the emphasis on taking their chances better in future.
"We've done a lot of work in front of goal," said Favre. "We want to improve, both up front and at the back.
"We are making progress, but we will still make even more. We have a very good squad and it's up to me to find the right balance and blend."
That will mean not neglecting the defence, even though they are the home team on Saturday.
Hannover, buoyed by a 2-0 win over Wolfsburg last weekend, will arrive at the Borussia Park stadion looking to carry on from where they left off in the Lower Saxony derby.
"We've just got to play our away games the same way as we do at home," said their coach Mirko Slomka at a press conference.
He has a new tool to work with this weekend with defender Marcelo arriving from PSV Eindhoven.
"My first impressions in Hannover are fantastic," said the stopper. "My team mates have welcomed me well and I saw in my first training session how much quality we've got.
"I think qualifying for the Europa League is definitely possible. We have a team which is capable of qualifying and if we carry on playing the way we did against Wolfsburg last weekend, then that's going to be possible.
"What matters is we believe in this aim. If the coach picks me, then I'm ready."
Gladbach goalkeeper Christofer Heimeroth is a doubt due to a flu virus while Christian Pander is unavailable for the Reds.
