RB Leipzig manager Julian Nagelsmann wants to see his team show aggression against Manchester United.
The Germans are without several key games for the UEFA Champions League group stages clash.
But Nagelsmann still has a very good squad at his disposal, and will know they can cause United problems.
The coach was asked about the upcoming game and their English opponents.
"I think the start of Manchester United's season wasn't that good but the last games I think went in the right direction," Nagelsmann told reporters.
"We know that they are very good and very tough to defeat, especially when you talk about the forwards or the offensive midfielders.
"(They have) a lot of qualities in the final third and we have to be aware of these situations. We have to close the space behind our defensive line.
"If we are very aggressive and we are watchful on these situations, then we are self-confident enough to talk about winning the game tomorrow.
"We prepared different formations. They played a different formation against PSG and Newcastle, and other teams in the league, they did it a different way.
"We've tried to solve the situation. We will see the starting line-up tomorrow and then I think we are well prepared.
"As I mentioned, we are self-confident enough - our start in the league was very good, start in the cup and also the Champions League - to talk about winning the game tomorrow."
