Given that Cody Gakpo was heavily linked with a transfer to Manchester United in the months leading up to his surprise switch to Anfield, it was, perhaps, inevitable that he would set the tone for one of the most memorable triumphs in recent Liverpool history.
The Dutchman left Fred trailing in his wake before cutting in from the left-hand side to sweep a low strike beyond David de Gea into the far corner.
In the end, Gakpo's fine strike on the stroke of half-time turned out to be the prelude to a second-half rout: he would go on to help himself to a second, whilst Darwin Nunez and Mohamed Salah also bagged doubles. Roberto Firmino compounded Manchester United's misery in the dying embers of the game to make it 7-0 to the Reds.
