1). Liverpool 4-0 Barcelona (2019 Champions League semi-final second leg)
The task was ominous. Liverpool needed to overturn a 3-0 deficit to Lionel Messi’s Barcelona, and without the injured Mohamed Salah and Roberto Firmino. Liverpool were relentless in their intensity; Barca could not live with Jurgen Klopp’s heavy metal football. Two goals apiece for Divock Origi – the second a moment of ingenuity from a corner kick by Trent Alexander-Arnold – and Georginio Wijnaldum saw Liverpool reach a second successive Champions League final. The sight of the entire Liverpool squad and backroom staff linked arm-in-arm as the Kop serenaded them with You’ll Never Walk Alone will live long in the memory. Getty Images
