Manchester United manager David Moyes was charged with misconduct by the Football Association on Friday after criticising match officials after his side's defeat by Sunderland on Tuesday.
Moyes said United were "playing referees as well as the opposition" following a 2-1 League Cup semi-final first leg reverse at the Stadium of Light on Tuesday, his side's third defeat in a row in all competitions.
"Manchester United manager David Moyes has been charged for misconduct by The FA in relation to post-match media comments he made following his side's game against Sunderland on Tuesday 7 January 2014," an FA statement said.
"It is alleged the comments called into question the integrity of the match officials appointed to that fixture and/or appointed to Manchester United fixtures generally, and/or implied that such match officials are motivated by bias; and/or brought the game into disrepute, in contravention of Rule E3(1)."
Moyes has until 6pm local time (1800GMT) on January 15 to respond to the charge.
The Scot questioned the awarding of a free-kick that led to Sunderland's opening goal and a penalty, having already said it was "scandalous" United were not awarded a late penalty against Tottenham Hotspur at Old Trafford.
"I feel we are having to play the opposition and the referees. We are all just laughing at them at the minute," Moyes said Tuesday.
Liverpool boss Brendan Rodgers was fined £8,000 ($13,177) and warned as to his conduct on Thursday after admitting a similar charge.
