Real Madrid provide Alexander-Arnold’s injury update: Will he miss the Barcelona clash in La Liga?

Real Madrid’s 2–1 win in their 2025–26 UEFA Champions League opener against Olympique Marseille came with a downside. One of the major setbacks was the injury to Trent Alexander-Arnold, who is now set to miss several matches this season — casting doubt on his potential involvement in the first Clasico against Barcelona.

Alexander-Arnold had to be substituted early in the match against OM due to a muscle issue, prompting head coach Xabi Alonso to bring on Dani Carvajal to continue the match at right back.

On Wednesday, Real Madrid released an update on the English defender. “Following tests carried out today by the Real Madrid Medical Services on our player, Trent Alexander-Arnold, he has been diagnosed with a muscle injury to the biceps femoris in his left leg. Further updates will follow,” the club stated on their official website.

Although the announcement from Los Blancos confirmed the nature of the injury, it did not include details on the severity or a projected recovery timeline. However, reports from Marca and Diario AS indicate that Trent is expected to be sidelined for a significant period — estimated between six and eight weeks.

If those estimates are accurate, and Alexander-Arnold is indeed out for between a month and a half to two months, he will miss a substantial number of games. He has already been ruled out of this Saturday’s La Liga match against Espanyol and could also miss at least four additional league fixtures and two Champions League group stage matches.
