Impact on Real Madrid’s Defence
The injury occurred just three minutes into Alexander-Arnold’s Champions League debut for Real Madrid last night when he was forced off due to acute pain in his left leg. He was replaced by Dani Carvajal. Prior to this, Alexander-Arnold had remained in Madrid during the international break and showed no signs of muscle fatigue before the match.
This setback is particularly significant as Alexander-Arnold had not yet found his best form for Real Madrid and will now be unable to feature until November at the earliest.
Key Matches to Be Missed
The injury timeline ruled Alexander-Arnold out of several crucial fixtures. He is confirmed absent for El Clásico against Barcelona scheduled for 26 October, as well as the high-profile clash with Atlético Madrid set for the coming weekend. Additionally, he will not be available for Champions League group stage matches against Kairat and Juventus. There remains some hope that he could be fit for the away fixture against Liverpool on 4 November.
Defensive Personnel Challenges
Alexander-Arnold’s enforced absence compounds Real Madrid’s defensive issues. Manager Xabi Alonso is already dealing with the injuries to Antonio Rüdiger and Ferland Mendy. Complicating matters further, Dean Hausen and Dani Carvajal are serving suspensions following red cards received in La Liga and the Champions League, respectively.
Since joining Real Madrid, Alexander-Arnold has made five appearances across all competitions this season.
