Trent Alexander-Arnold has signed a new Liverpool contract, it was confirmed on Tuesday.

Liverpool revealed on their official website that the right-back, 18, has put pen to paper after being rewarded for his impressive progress.

Alexander-Arnold, who can play at either right-back or in midfield, has been joined by midfield anchorman Kevin Stewart, 23, and striker Ben Woodburn, 17, in signing long-term deals.

Liverpool did not specify the length of Alexander-Arnold’s new contract but the Liverpool Echo report that it will run for five years until 2021.

The teenager took to his personal Twitter account on Tuesday to express his delight at reaching an agreement with the Premier League leaders.

Alexander-Arnold delivered a buccaneering display on his Liverpool debut last month as a youthful side beat Tottenham 2-1 in the League Cup fourth-round to secure a quarter-final clash against Leeds.

The 18-year-old academy product played 68 minutes of the clash at right-back before being withdrawn by manager Jurgen Klopp after collecting a yellow card in the opening period for a rash tackle.

Alexander-Arnold has been on the club’s books since the age of six. He’s now a regular at Melwood but is sent to the Academy for some sessions to aid his development.

The teenager impressed former Liverpool manager Souness with his performance against Spurs.

“He looks extremely athletic, quick, aggressive,” Souness told Sky Sports 1’s live coverage of the match. “He has all the attributes to be a top player. He’s in great shape for a ground-coverer… light on his feet, and he’s aggressive.

“He got himself in trouble once in the first half, but overall I thought he was very good. Trent stayed on his feet, as good coaches teach you, in the second half. I thought he had a super game.”

Two goals from Daniel Sturridge were enough to secure Liverpool’s safe passage into the last eight of the competition in which they were runners-up last season.
