In 2021, Alexander-Arnold put pen-to-paper on a four-year contract. Two years later, Jurgen Klopp made him vice-captain.
Fellow Liverpudlian Jamie Carragher, who spent his entire career at Anfield, summed up the emotions of the fans.
«I think the manager will be shocked by how vociferous the reaction was,» Carragher said on Sky Sports.
«That might be his last game for Liverpool but, if frustrated with Trent, sing Bradley’s name, sing Gerrard’s name. Don’t boo your players because it opens you up to criticism.
«Liverpool supporters think playing for Liverpool is the utmost and when you’re a local player, like Trent is, like I was, you can’t see yourself as bigger than the club.
«Supporters of any club wouldn’t want to hear this, but most players in that dressing room probably want to play for Real Madrid.
«I’ve been in that dressing room, with players who have left us for Real Madrid or Barcelona.
«It’s sometimes really hard for supporters. You feel like they fall for it every time, that a player loves them and then moves on.»
Former Manchester United and England defender Rio Ferdinand posted on X: «I can’t believe Liverpool fans booing one of their own.
«I understand that some of you guys are not happy with his decision etc BUT to boo Trent after he has won the lot with you is baffling! Didn’t cost you a penny.»
