Manchester United have been charged by the Football Association for failing to conduct themselves in an orderly fashion during their Premier League defeat against Liverpool on Sunday.
United's players surrounded referee Craig Pawson midway through the opening period after Virgil Van Dijk collided David De Gea.
Roberto Firmino subsequently scored, but his goal was ruled out following a VAR review of Van Dijk's clash with the United goalkeeper.
United have until Thursday to respond to the charge.
De Gea dropped the ball following Van Dijk's challenge. United failed to clear their lines with Firmino appearing to double Liverpool's advantage at Anfield.
A furious De Gea led United's protests, rushing over to Pawson to vent his frustration.
The Spaniard, who was booked for his actions, was joined by a number of his teammates in surrounding the referee.
A VAR review of the incident deemed De Gea had been fouled and Firmino's goal was disallowed, but Liverpool still went on to win the game 2-0 and extend their lead over Manchester City to 16 points.
Manchester United manager Ole Gunnar Solskjaer did not criticise his players after hearing about the FA charge.
"Maybe I shouldn't talk too much about that. Let's get that decision done but... it's overturned. Our players... I didn't see... I reacted myself because everybody could see it was a foul."
