It is in these moments that all the great occasions are remembered: Saint-Etienne, Auxerre, Borussia Dortmund and Barcelona — the nights when Anfield witnessed footballing miracles.
Those games, with the colour and drama and goals, are what Liverpool in Europe have come to symbolise, so it is inevitable there is expectation that a similar scenario will unfold this evening when Real Madrid arrive in town.
Judging by the reserved demeanour of Jurgen Klopp and Andrew Robertson, though, you sense if another act of escapology is conjured it might be regarded as Liverpool's greatest comeback yet.
