Lisandro Martinez red card controversy

Manchester United defender Lisandro Martinez was shown a controversial red card for pulling the hair of Leeds United striker Dominic Calvert-Lewin during a 2-1 defeat at Old Trafford.

Interim manager Michael Carrick expressed fury at the decision, which could leave the team with a defensive crisis ahead of their clash with Chelsea.

While some pundits argued the punishment was harsh, the PGMOL confirmed that hair-pulling is classified as violent conduct under current rules.

The loss ended United's 45-year unbeaten home run against their Yorkshire rivals and has intensified the pressure on Carrick's audition for the permanent role.

The club is now reportedly considering an appeal to have the three-match ban overturned.
