The 23-year-old found the head of Sadio Mane with typical pinpoint accuracy from a free-kick to nod the Reds into a deserved lead in the 39th minute.
Not content with the one assist on the night, Alexander-Arnold was involved in the fourth and final goal as the marauding Scouse full-back found an unmarked Takumi Minamino at the back post.
Those involvements and the clean sheet saw the ace named Man of the Match – as voted by supporters.
̶5̶0̶ 𝟱𝟭 assists for the Reds!

The assists took Alexander-Arnold’s tally to nine for this season across all competitions.
On what was a near-perfect night for Jurgen Klopp’s side, there was one moment of concern as despite playing on after picking up a knock, Diogo Jota headed straight to the dressing room after being replaced.
Experts on the suject InjuryMechanisms took to Twitter to speculate on the possible extent of the damage suffered.
Left knee injury for Liverpool’s Diogo #Jota. Fall onto flexed knee before GK collision.

Liverpool can ill-afford many more absentees as Divock Origi, Naby Keita, James Milner, Curtis Jones, Harvey Elliott and Roberto Firmino all remain sidelined.
READ LIVERPOOL VERDICT
Absolutely outstanding once again from the West Derby-born sensation.
Rarely have we seen such an instrumental footballer, certainly from right-back.
Valued at £67.5million (Transfermarkt), the academy graduate has reinvented the role and looks to have plenty more to offer yet.
As for Jota, Kopites will have everything crossed it was merely precautionary and a midweek rest against FC Porto is more than plausible having already won the UEFA Champions League group.
