Footage has surfaced, meanwhile, of the moment Alexander-Arnold appeared to pick up the knock, with the 25-year-old seemingly getting injured in a duel with Gabriel Martinelli.

That happened in the 68th minute of the game, with Alexander-Arnold seeing out the remained of the match despite having suffered the blow.

Pretty mad to think Trent played half an hour with a tear in his knee.

Looked nasty tbh. pic.twitter.com/4nWp8LCk54

The moment Trent Alexander-Arnold picked up the injury that will keep him out for ‘a few weeks’ has seemingly been revealed

He appeared to hurt his knee during a duel with Gabriel Martinelli (not pictured) with more than 20 minutes of the game remaining

Alexander-Arnold, who put in the cross that Jakub Kiwior headed into his own goal for the opener, was beaten down the left side of attack by Martinelli just as the injury happened, with it unclear if he picked up the injury in the one-on-one.

He seemed to take a few steps after the Brazilian had got round him before feeling the pain, remaining off the pitch for a few seconds as Liverpool re-gained the ball.

He limped back onto the field of play but was clearly in some discomfort, and he was beaten by Martinelli again moments later.

The defender could be notably seen limping at full time and it has now been confirmed he will be out of action for a short period of time.

This video after the game against Arsenal is starting to make a lot of sense. Hopefully it isn’t too serious. 🤞🏻🔴 #LFC

The defender played the remainder of the game, putting in the cross that led to Liverpool’s first goal

The news is a big blow to the Reds, who will already be without key man Mohamed Salah (right) for a few weeks due to his participation at the African Cup of Nations
