Trent joined the Academy at the age of six and made his first-team debut for the club in October 2016.
He began the 2014-15 campaign as captain of the U16 team, made his U18s debut in 2014 and became captain of Neil Critchley's side.
Two months after an impressive outing for the first team in the pre-season friendly win at Swindon Town in August 2015, he maintained his ascent by penning a professional contract with the Reds.
And a year on, having been named on the bench for the Premier League opener against Arsenal at Emirates Stadium, Alexander-Arnold made his senior debut in a League Cup victory over Tottenham Hotspur at Anfield.
Trent made his first Premier League start for the club during the 1-1 draw with Manchester United at Old Trafford on January 15, 2017.
And on July 7 of that year, he committed his future to the club, penning a new long-term contract.
In 2017-18 Alexander-Arnold made his big breakthrough. With Nathaniel Clyne ruled out through injury, Trent shared the right-back berth with Joe Gomez.
Alexander-Arnold made 33 first-team appearances in total including a start in the 2018 Champions League final.
He was then handed an England debut before being given a place in Gareth Southgate's squad for the 2018 World Cup in Russia.
The following season, the club announced on January 19, 2019, Alexander-Arnold had signed a new long-term contract, extending his lifelong love affair with the Reds into the years to come.
