Alexander-Arnold has played over 40 games in each of the previous three campaigns under Klopp, including starting the Champions League final win over Spurs in 2019 – a year that also saw him make the shortlist for the Ballon d'Or.
The 22-year-old excelled as Liverpool were crowned champions the following season, scoring four goals and providing 13 assists – only Manchester City midfielder Kevin De Bruyne (20) supplied more – while playing in every league fixture.
While he struggled to replicate the same form in 2020-21 in a defence that lost key personnel to serious injuries, he still made 34 starts and managed two goals, one of which was a dramatic long-range late winner at home to Aston Villa in April.
"I live the dream every day really. Being able to represent the club and to be in and around names and players, and obviously managers and staff, that are world class every day is a privilege for me and I'm very fortunate to be in the position I am," Alexander-Arnold added.
Ruled out of Euros
Gareth Southgate selected Alexander-Arnold in his 26-man England squad for this year's European Championship, despite speculation he would be a high-profile absentee from the final list.
