Lisandro Martínez was spotted in Manchester United training yesterday, as the club doctor confirmed he is fit to start against Athletic Club

Manchester United have suffered a major setback with Lisandro Martínez sustaining a serious injury that could sideline him for an extended period. The Argentine defender tore his cruciate ligament during the final minutes of their clash against Crystal Palace, specifically in the 82nd minute. He had to be stretchered off after receiving immediate medical attention on the pitch.
The club later confirmed the severity of the injury, stating that it is indeed a cruciate ligament tear. While they are still evaluating the full extent of the damage, early indications suggest that surgery will almost certainly be required. As a result, Martínez is now ruled out for the remainder of the current season and may even miss the start of the next campaign, including vital pre-season preparations.
Cruciate ligament injuries, especially those involving the ACL, generally take about six to nine months for full recovery. If Martínez undergoes surgery in the near future, he could potentially return to action between January and March 2026. However, any complications or setbacks in rehabilitation could extend that timeline.
This injury is a huge blow to United’s defensive line. Martínez is known for his aggression, composure, and technical ability—qualities that are hard to replace. His absence leaves the squad vulnerable, especially with other defenders like Maguire struggling for consistency and Varane reportedly on the way out.
To make matters worse, this development intensifies the need for United to reinforce their defense in the upcoming transfer window. With Martínez out and the current backline under scrutiny, the club will now likely escalate efforts to secure a new centre-back, possibly targeting someone with the reliability and presence Martínez brings to the pitch. Interestingly, Athletic Club could become part of the conversation, as United may turn their attention there in their search for a suitable replacement.
