Real Madrid Lose Antonio Rüdiger to Serious Injury in Major Setback for Xabi Alonso

Real Madrid’s perfect start to the 2025-26 season has been overshadowed by a hammer blow: Antonio Rüdiger has been ruled out for months after suffering what the club described as a “serious” muscle injury. The German centre-back’s absence threatens to derail Madrid’s early-season momentum and leaves Xabi Alonso facing a defensive headache ahead of a crucial run of fixtures.

Antonio Rüdiger Injury Confirmed – Months on the Sidelines

In a statement released on Friday, Los Blancos confirmed that Rüdiger has sustained an injury to the rectus femoris muscle in his left leg. While the club have not publicly stated a return date, reports from Sky Sports Germany claim that the 31-year-old could be sidelined until December – a major blow considering the fixtures on the horizon.

If the prognosis proves accurate, Rüdiger will miss both of Real Madrid’s UEFA Champions League group-stage clashes against Juventus and Liverpool in October, as well as the first El Clásico of the season against Barcelona on October 26. That match at the Santiago Bernabéu is typically a title-shaping encounter, and losing such an influential figure beforehand is the last thing Alonso would have wanted.

Rüdiger has been a warrior since arriving from Chelsea in 2022, bringing aggression, leadership, and a winning mentality to Madrid’s back line. His absence is more than just a personnel issue – it takes away a presence that has often lifted Madrid in high-pressure moments.

Alonso’s Defensive Options Put to the Test

Xabi Alonso, who stepped into the Madrid dugout in the summer after Carlo Ancelotti’s departure, has so far navigated life at the Bernabéu impressively. His side have opened their La Liga campaign with three wins from three, dispatching Osasuna, Real Oviedo, and Mallorca. But the loss of Rüdiger now places extra scrutiny on his ability to rotate and manage resources.

For now, the likely starting centre-back pairing will feature Eder Militão alongside new signing Dean Huijsen. Militão, while world-class when fit, has himself battled injury setbacks over the past two seasons. His ability to stay healthy will be crucial. Huijsen, meanwhile, has been impressive since arriving but is still learning the demands of playing for a club like Real Madrid, where every mistake is magnified.

Behind them, Alonso can call upon David Alaba, though the Austrian has struggled for consistency and fitness over the past year, and youngster Raúl Asencio, who may now get more first-team minutes than expected. Madrid have long prided themselves on squad depth, but this situation will stretch them to their limits, particularly with the club competing on multiple fronts.

Timing Could Not Be Worse

Rüdiger’s injury comes at a particularly difficult juncture for Madrid. October is shaping up to be one of their busiest months of the season, featuring high-stakes Champions League fixtures, domestic matches against tricky opponents, and, of course, El Clásico.

The German’s physicality and leadership will be sorely missed when Madrid face teams like Liverpool and Juventus – sides that are relentless in attack and will look to exploit any weakness in the heart of Madrid’s defence. Alonso will need to rely heavily on his midfield shield – players like Aurélien Tchouaméni and Eduardo Camavinga – to protect the back four and limit exposure.

A Return to San Sebastián Adds Emotion to the Challenge

Before turning attention to Europe, Madrid must first navigate their weekend clash against Real Sociedad, a game that carries extra emotion for Alonso. La Real is where the Madrid coach’s football journey began, and he made 124 appearances for the Basque side before moving to Liverpool. Now, he returns to the Reale Arena as a manager for the first time, hoping to keep Madrid’s perfect start intact despite the blow of losing one of his defensive anchors.

Sociedad, known for their pressing game and quick combinations, will look to test the Militão-Huijsen partnership early. It could be a baptism of fire for the young Dutch defender, who will be tasked with neutralising the likes of Mikel Oyarzabal and Takefusa Kubo.

Madrid’s Mentality Will Be Tested

If there’s one thing Madrid have been known for throughout their history, it’s their ability to respond to adversity. From injury crises to suspensions, they have often found a way to step up when the odds are stacked against them. Alonso will be keen to channel that spirit and maintain the team’s momentum heading into the international break.

Veterans like Luka Modrić, Dani Carvajal, and Nacho Fernández will be vital voices in the dressing room, helping to keep standards high and confidence intact. Meanwhile, attacking stars such as Vinícius Júnior and Kylian Mbappé will be expected to take on even more responsibility in the final third, ensuring Madrid outscore opponents if defensive solidity is compromised.

Looking Ahead – Can Rüdiger Return Before the Year Ends?

Madrid’s medical team will closely monitor Rüdiger’s recovery, but muscle injuries of this severity often require patience. Any attempt to rush him back could risk aggravation and a longer absence – something Madrid cannot afford given the demanding second half of the season that includes the Champions League knockout stages and the Club World Cup.

For now, the focus shifts to survival: grinding out results, keeping pace with Barcelona at the top of La Liga, and ensuring that the squad stays as healthy as possible through this critical period.

Losing Antonio Rüdiger for months is a cruel blow for Real Madrid just as their season was gathering momentum. How Alonso and his squad respond to this challenge may well define their campaign. If they can weather the storm and stay competitive until December, Rüdiger’s eventual return could feel like a major winter signing – and could give Los Blancos the defensive boost they need for a title charge in 2026.
