Lisandro Martinez Red Card Row

The controversial incident has sparked a heated debate among pundits and former referees over the interpretation of the rules.

Carrick described the red card as 'absolutely shocking' and hinted that the club would appeal the three-match ban.

Former referee Mark Halsey argued that the dismissal was harsh, while others pointed out that hair-pulling is a clear violation of the Ifab laws.

The loss of Martinez comes at a critical time for United, who are facing a defensive crisis ahead of a pivotal clash with Chelsea.
