The 25-year-old England international, who has made 18 Premier League appearances for Liverpool this season, suffered the injury during Sunday’s 2-0 FA Cup third-round win at Arsenal.

“Trent hyperextended his knee. So he has a little tear in the lateral ligament of his knee and he will need time to recover,” Lijnders said.

“Hopefully three weeks, with the winter break in between,” he told reporters.

Liverpool have a gap of 11 days between tomorrow’s League Cup semifinal against Fulham and their next league match at Bournemouth.

“Hopefully, he can come back to where he was. Because this guy was decisive in all the games and was the one who created constantly for us from deep and gave the team a high level of flexibility. We will really miss him,” Lijnders added.

Alexander-Arnold, occasionally used as a midfielder, has scored two goals and provided three assists in the league this season.
