Manchester United have been charged with failing to ensure their players 'conducted themselves in an orderly fashion' during Sunday's Premier League match against Liverpool at Anfield.
The incident followed Roberto Firmino's disallowed goal, when referee Craig Pawson initially did not give a free-kick for what appeared to be a foul by Virgil van Dijk on David de Gea.
The United players surrounded the referee to complain about the decision. It was eventually overturned with the intervention of VAR.
Pawson dished out a yellow card to De Gea for his reaction to the decision prior to the goal being disallowed.
