Jurgen Klopp has answered the all-important question.
The little African opened the scoring for RB on the day before he threaded a stunning through ball to Timo Werner who scored the victor in a famous match for the east German club.
"There will be a lot of moments where we have to defend and we worked on that, we tried to work on that because we respect the quality of Bayern Munich a lot - speed, technique, experience, it's all there what you need to be successful".
I don't think we'll see 0-0 tomorrow. Their defence isn't as good as it once was, said Hamann, and they have a habit of giving up too many chances in games that they control going forward.
"Thank god we don't have to make that decision today". We've got them, but that depends on what happens on the pitch on the night. "I've experienced it a couple of times where our crowd pushes us from 100 to 120 or 140 per cent".
"Tomorrow we're playing against an opponent that's the most hard draw", the German told a news conference on Monday evening.
Klopp knows what his club's supporters would choose if they had to decide between the two competitions, but the Reds boss is determined to target victory in both. The full focus is on this game and then after, we can turn our attentions to United. We are a really strong side and that is what we have to show.
The prolific Pole won two Bundesliga titles under Klopp when the pair were together at Borussia Dortmund and also lost the Champions League final against Bayern in 2013 before Lewandowski was lured to Bavaria a year later.
"When you look at us, we are not as consistent as before", Kimmich added.
