Lisandro Martinez is set to leave Manchester United at the end of his current contract, with the 28-year-old Argentine defender showing no desire to extend his stay at Old Trafford beyond the 2026-27 season.

The situation came to a head following Martinez's public criticism of unnamed figures within the Manchester United hierarchy after the club's UEFA Champions League defeat to Atletico Madrid at the Wanda Metropolitano. His comments ignited a firestorm inside the dressing room and beyond, calling into question the club's direction under technical director Jason Wilcox — an implicit rebuke of the summer recruitment process.

Instagram clarification fails to douse the flames

Martinez later turned to Instagram in an attempt to soften the blow, stating that his words stemmed from frustration and calling for unity at Manchester United going forward. The gesture did little to eliminate the underlying tension.

Manager Michael Carrick also moved to draw a line under the dispute, insisting the matter had been resolved internally and that it would not disrupt the squad's preparations. Nevertheless, doubt continues to hang over Martinez's future at the club.

A strong season overshadowed by fallout

The row stands in sharp contrast to what had been a positive first full season under Carrick. Manchester United finished third in the Premier League in 2025-26, earning a return to the UEFA Champions League — only to be dominated by Atletico Madrid in Europe, a result that appeared to push Martinez's frustration beyond a breaking point.

His contract at Old Trafford runs until the summer of 2027, and Manchester United do hold a 12-month extension option. However, according to the Manchester Evening News, the likelihood of that option being triggered has receded sharply given the current climate.

Atletico Madrid circle back

Should Martinez depart next summer, a move to Spain is his preference — and in a striking twist, Atletico Madrid are among the clubs linked with the defender. The same club whose stadium bore witness to his burst of public anger could yet become his next home.

With both parties appearing increasingly unlikely to reach a long-term agreement, Manchester United face a difficult decision over one of their most passionate players — and, potentially, a costly sale.
