Liverpool's assistant coach, Pep Lijnders, confirmed the news a day before the first leg of the English League Cup semi-finals against Marco Silva's Fulham.

Liverpool made an official announcement on Tuesday, confirming that Trent Alexander-Arnold has sustained a knee injury that will sideline him for an unspecified period described as 'a few weeks.' 

This announcement came to light in the lead-up to the crucial first-leg clash of the English League Cup semi-finals, where Liverpool is set to host Marco Silva's Fulham on Wednesday at 8:00 PM.

Pep Lijnders, Liverpool's assistant coach, provided insights into the nature of Alexander-Arnold's injury during the pre-match press conference. He disclosed that the talented defender had suffered a hyperextension of his knee in the recent game, which saw Liverpool secure a 2-0 victory against Arsenal in the FA Cup. 

The injury report indicated a minor tear in the lateral knee ligament, necessitating a period of recuperation. Trent Alexander-Arnold underwent a comprehensive examination to assess the extent of the damage, confirming his unavailability for the upcoming matches. Lijnders expressed hope that after a period of rest, Alexander-Arnold would regain his previous form.

According to reports from Sky Sports, it is estimated that Alexander-Arnold could be sidelined for roughly three weeks. This unfortunate setback implies that he will be unable to participate in both legs of the semi-final against Fulham, as well as in the Premier League encounter against Bournemouth. Furthermore, the injury puts into question his availability for Liverpool's league match against Chelsea on January 31st and their visit to Arsenal on February 4th.

Alexander-Arnold's absence is keenly felt by Liverpool, given his substantial contributions during the current season, including two goals and nine assists in 25 appearances. The injury raises concerns about Liverpool's defensive stability and the impact on their performance in these crucial upcoming fixtures. As the team navigates this challenging period, the hope is that Alexander-Arnold can make a swift and full recovery to bolster Liverpool's pursuit of success in both domestic and cup competitions.
