Sunderland manager, David Moyes, has been charged with misconduct after being sent off at Southampton on Wednesday.
The Football Association said it was alleged that “Moyes used abusive and/or insulting words towards a match official.”
The official had let fourth official James Adcock know about it – and referee Chris Kavanagh promptly sent Moyes to the stands.
Speaking after the game, Moyes explained why he’d been sent to the stands:
“I was sent off for leaving my box and sent off for swearing, so it was correct.
“The decision to send me off was correct. It was the fourth official who chased me down the touchline.
“I swore at him which I shouldn’t have done. No problem, I deserved to be sent off.
“But I think they should look at the reason why I was [upset].”
On the penalty claim, Moyes added: “I think if you see it again, you’ll see it’s a stonewaller.
“It was inside the box and Yoshida fouled Victor, going across him. It should definitely have been a penalty kick.
“I’m disappointed we are out of the cup, that’s the big thing. We should have had a chance to take a penalty kick and if we had scored it, to go to extra-time, but it didn’t happen.”
Southampton were drawn away to Arsenal in the quarter-finals after their 1-0 win.
He has been given until 18:00 BST on Tuesday to respond to the allegation.
The incident took place when Referee Chris Kavanagh waved away appeals for a foul on Sunderland striker Victor Anichebe in the penalty area.
Sunderland lost 1-0 to their hosts as they crashed out of the EFL Cup.
