Julian Nagelsmann says RB Leipzig have analysed what went wrong against Manchester United in their last meeting back in October.
The Red Devils claimed an impressive 5-0 win over the Germans at Old Trafford.
Leipzig must beat United on Tuesday to qualify for the Champions League knockout rounds, while the Premier League giants only need a draw.
And Nagelsmann is aware of the challenges his team face against United.
"Well, of course the result doesn't play such a big role because it's different pre-conditions," the 33-year-old said in his press conference.
"With a victory we will make it into the next round. Of course, we cannot have the match equalised because we lost a direct competition with them [last time] but we have analysed the match, seen where the players weren't so good in certain situations.
"We lost maybe some duels in the first leg, we tried to have the numeric advantage, we want to recover a lot of balls and be better in the game.
"We were a little too afraid at the start, we can add a lot and improve, especially in the final third we can do a lot better. They defended really well but we can't say they played really well. We have to create and search for our opportunities.
"We are aware that we are facing United. If they are trailing, they can turn around the match, they can still win matches. They've shown that in the last matches, even after going behind, so we have to wait until the referee ends the match actually. We have to fight until the very end to get the three points."
