According to a report by Sky Sport on Sunday, October 18, 2026, Manchester United defender Lisandro Martínez was substituted at half-time after experiencing a thigh problem, with manager Michael Carrick confirming the issue. The development has raised concerns about the Argentine’s fitness as United prepare for their upcoming fixtures.

Martínez’s injury could be a setback for Manchester United, given his importance to the team’s defensive structure. The Argentine international is known for his aggressive approach, strong tackling and ability to play the ball out from the back.

His presence also helps United build attacks from defence and maintain possession under pressure. Any prolonged absence could therefore force Carrick to reconsider his defensive options and make adjustments to the team’s formation.

The decision to withdraw Martínez at half-time suggests the club was unwilling to risk aggravating the problem. However, the available information does not establish the severity of the injury, and further medical examinations may be required to determine how long he could be sidelined.

Manchester United supporters will be hoping the problem is not serious and that the defender can return to training soon. Thigh injuries vary in severity, making it difficult to predict a recovery period without a confirmed medical assessment.

Martínez has become an important figure in United’s defence because of his determination, physical commitment and ability to retain possession when opponents apply pressure. His understanding with his defensive teammates also helps the club deal with dangerous attacking opposition.

If the defender is ruled out of upcoming matches, Carrick may need to consider alternative defensive partnerships. The manager will be expected to ensure that any replacement can maintain the organisation and stability needed at the back.

The injury update comes as attention remains focused on Carrick’s position as Manchester United manager. The club’s performances and future direction continue to attract interest, making the fitness of key players an important consideration for the coaching staff.

The immediate priority will be to establish the full extent of Martínez’s thigh problem before determining whether he will be available for United’s next match.

Manchester United have yet to confirm a recovery timeline in the information provided. Supporters will be awaiting further updates from Carrick and the club’s medical team.

For now, Martínez’s condition remains uncertain, with United hoping his half-time withdrawal was a precaution and will not lead to an extended spell on the sidelines.
