Trailing 3-0 from the first leg of the semi-final, the Reds required a practically perfect performance against Lionel Messi and co at Anfield to stand any chance of qualifying for a second successive final.
Cue, one of the all-time great European displays and celebrations.
Divock Origi’s early strike provided a sense of hope that was transformed into real opportunity when substitute Georginio Wijnaldum netted twice in as many minutes after the interval.
Then, amid an Anfield cacophony, Trent Alexander-Arnold’s instantly-iconic quick corner teed up Origi to swipe home a clinching fourth and book a trip to Madrid for Jürgen Klopp’s soon-to-be European champions.
