The Englishman suffered a muscular injury to the rectus anterior quadriceps in his left leg during his side's 3-0 victory at Athletic Club. This was confirmed by medical tests carried out on Thursday morning and officially announced by the club.
This is a major setback for the right back, who had finally found the consistency needed to showcase his many talents, but now faces another spell on the sidelines with what is his third injury since joining Real Madrid.
Barring an unexpected and miraculous recovery - and given his injury history, the club won’t take any risks - Alexander-Arnold is not expected to play again until the start of 2026. He already missed five weeks after his previous hamstring problem.
With Dani Carvajal still out, Xabi Alonso’s options are to move Fede Valverde back to right back, trust Reaul Asencio - who already filled in for Trent at San Mames - or turn to Eder Militao, who has played that position for Brazil.
