Real Madrid has been dealt a significant blow with the news that their new signing, Trent Alexander-Arnold, has been ruled out indefinitely due to a hamstring injury. The unfortunate incident occurred during the Champions League match against Olympique de Marseille at the Santiago Bernabeu.

The 26-year-old right-back, who joined Real Madrid this summer, started the match against Marseille, marking his Champions League debut for the club. However, his debut was cut short just two minutes into the game when he felt a sharp pain in his left leg. After receiving medical attention on the field, he was replaced by Dani Carvajal.

Real Madrid has officially confirmed that Alexander-Arnold sustained a muscle injury in the hamstring of his left leg. While the club's statement didn't specify the length of his absence, journalist Arancha Rodriguez reported that he would be sidelined for six to eight weeks. If the timeline is maintained, he will likely make his comeback in early November.

This injury is a major setback for Real Madrid, as Alexander-Arnold is set to miss several important matches, including the Madrid derby against Atletico Madrid later this month. An absence of six weeks would also make him doubtful for the first El Clasico of the season against Barcelona, scheduled for the weekend of October 26. Furthermore, he is likely to miss the return to Anfield, where Real Madrid will face Liverpool in the Champions League on November 4.

To add to Real Madrid's woes, Dani Carvajal, Alexander-Arnold's replacement, was shown a straight red card in the same match against Marseille for head-butting the goalkeeper. Carvajal could face an extended suspension from UEFA, potentially ruling him out for three Champions League games. This would leave Real Madrid without a recognized right-back for their match against Kairat and potentially the clash against his former club Liverpool.

Real Madrid manager Xabi Alonso acknowledged the situation and said the team will need to find solutions. He suggested that Alexander-Arnold will be ruled out of Saturday's La Liga encounter against Espanyol. Alonso mentioned that other players like Raul Asencio, Eduardo Camavinga, and Jude Bellingham could step up to fill the void.

Alexander-Arnold's injury also casts doubt on his chances of being selected for England's national team. He was previously omitted from the squad for the September break and is now unlikely to be available for the upcoming 2026 World Cup qualifying matches in October.

Despite the setback, Alexander-Arnold remains positive. He posted a message on his Instagram story, saying he would be back as soon as possible and stronger than before.
