Scarves will be held aloft and the words of the 1945 show tune belted out again at Anfield on Thursday, while there will also be a pre-match minute’s silence to mark the 27th anniversary of the 1989 Hillsborough disaster, in which 96 Liverpool fans lost their lives.
In addition, supporters of both clubs will hold up coloured mosaics forming ’96’.
On the pitch, Klopp’s most pressing selection dilemma concerns whether to keep faith with Daniel Sturridge up front or turn back to Origi, who followed up his goal in Dortmund with a brace in Sunday’s 4-1 defeat of Stoke City after coming on in place of Sturridge.
Captain Jordan Henderson will be absent after sustaining a season-ending knee injury in the first leg, with fellow England midfielder James Milner in line to inherit the armband.
Dortmund went into the tie as competition favourites, but struggled to cope with Liverpool’s pressing and were then held to a 2-2 draw by hated local rivals Schalke at the weekend that left them seven points below leaders Bayern Munich in the Bundesliga.
Dortmund coach Thomas Tuchel used the opportunity to rest eight first-team players, including star forwards Marco Reus and Pierre-Emerick Aubameyang, and will restore his big guns to his starting line-up on Thursday.
Like Klopp, whom he succeeded as head coach at first Mainz and then Dortmund, Tuchel has played down the significance of the first leg.
“I don’t care too much about the result in the first leg. I don’t think it will be that decisive,” he said.
“We are here to attack, we are here to score goals, to take risks and to enjoy the game. We are not here to feel our boundaries. We are here to feel our potential.
“We are clear we will have to play our best, but we feel ready for it. We don’t want to score one – we want two or even more.”
