The full-back was once again a creative fulcrum for the Reds as they stretched their lead at the top of the Premier League to 22 points by beating the Hammers at Anfield on Monday night.
A superb ball in from Alexander-Arnold teed up Georginio Wijnaldum to open the scoring early on with a fine header, and the No.66 then delivered for Sadio Mane to slot in an 81st-minute winner after West Ham had led 2-1 prior to Mohamed Salah’s equaliser.
The right-back’s Premier League assist tally for the season now stands at 12 in just 27 appearances and, post-match, he was asked whether he specifically seeks out a teammate with his crosses or instead looks to find dangerous areas.
