Manchester United's defender Lisandro Martinez was shown a red card in their 2-0 loss to Chelsea, worsening the club's crisis. The incident occurred in the 68th minute as Martinez fouled Kai Havertz, leading to a penalty and a further goal. The red card left United with 10 men for the remainder of the match, contributing to their defeat.

The red card has intensified scrutiny on manager Michael Carrick, who now faces mounting pressure to step down. Manchester United are 17th in the Premier League, just outside the relegation zone, after nine matches without a win. Carrick's position has been under review following the loss, with the board considering a potential sacking.

Martinez's dismissal has sparked criticism from former players and pundits. Joe Cole, a Chelsea legend, suggested Martinez's career at United may be over. A pundit from Match of the Day also questioned the lack of support from teammates. The incident highlights internal tensions within the team, with Martinez's actions seen as a self-sabotage.

This loss marks the third consecutive defeat for United under Carrick, deepening concerns about his leadership. The club's poor form has led to calls for a change in management, with the board reportedly close to making a decision. The situation remains critical as United look to recover from their worst run of form in decades.
