Manchester United are reportedly considering a fine for defender Lisandro Martínez after he publicly criticised the club’s leadership following their two-nil Champions League defeat to Atlético Madrid.

The Argentina international expressed frustration over the club’s summer recruitment and called for greater investment to strengthen the squad.

Martínez specifically questioned technical director Jason Wilcox, arguing that responsibility for the team’s struggles should not fall solely on the manager and players.

He later insisted he would not keep quiet about his concerns, adding to tensions over the club’s direction.

Reports by The Athletic’s Laurie Whitwell indicate that a financial sanction is considered likely, although other players reportedly share similar concerns about recruitment.

Martínez’s current contract runs until June 2027, with Manchester United holding an option to extend it by another year. However, the latest controversy has raised further questions about his long-term future at Old Trafford.

United are scheduled to face Leeds United in the Premier League on Sunday.
