Jurgen Klopp's return will, understandably, hog the headlines, but it looks set to be an epic clash nonetheless.
Liverpool may well begin the game as underdogs, but there's no reason why they won't be able to upset Thomas Tuchel's side. In all honesty, though, the Reds will have to be at their best to overcome the Bundesliga giants.
Anyway, you can watch the video of the two sets of fans singing 'You’ll Never Walk Alone' here:
One thing is for sure, if Liverpool manage to find the back of the net against Dortmund, then it's likely that Klopp will celebrate against his former club.
Speaking ahead of the contest, as per the Guardian, Klopp stated: "Of course I will celebrate. I did it when I went back to Mainz with Dortmund, and I was there for 18 years. If after seven years they don’t know me well enough that my team should score and I will celebrate, what can I say? It depends.
"If it’s in the first minute I don’t know, I won’t go running down the line. But if it’s important, decisive, in this moment that’s what happens. It’s not that I plan this but I will not take some pills to stop me from celebrating a goal.
"At Mainz they knew about it. We had a big celebration when I left and when I went back there it’s what they expected. I did everything for Mainz, I did everything for Dortmund and now I do everything for Liverpool – it is like it is.
"My father loved me but when we played something against each other he wanted to beat me. I needed 15 years to beat him for the first time but that wasn’t his problem and there was no doubt about our relationship. It’s a game, even if people are not always aware of it."
