Alexander-Arnold's injury occurred just three minutes into his Champions League debut for Real Madrid. He was forced to leave the game early, which was a setback for both him and his manager, Xabi Alonso. Additionally, teammate Dani Carvajal was also sent off during the match.

According to reports, Alexander-Arnold has been diagnosed with a muscle injury in his left leg. This is the second time in a short period that he has experienced a muscle complaint, having previously missed a match against Paris Saint-Germain in July.

Alexander-Arnold may also miss a return to Anfield in six weeks, which could be a significant blow to him. However, the severity of his injury will determine if he can recover in time for the match.

If Alexander-Arnold is able to make a full recovery before the match, he may face a chilly reception from the Anfield crowd. He left the Liverpool team during the summer transfer window under difficult circumstances.
