Sir Alex Ferguson and Carlos Queiroz have been charged with improper conduct after Manchester United’s FA Cup quarter-final loss to Portsmouth.
Following the 1-0 defeat, the United boss and his assistant were critical of referee Martin Atkinson and referees’ chief Keith Hackett.
Ferguson called Atkinson’s performance “not acceptable” and Queiroz branded him “a disgrace”.
A penalty converted by Portsmouth separated the sides, but Ferguson was unhappy that his side had been denied a spot-kick when Cristiano Ronaldo was blocked by Sylvain Distin.
“It’s absolutely ridiculous,” he said.
“I cannot explain it. Managers get sacked because of things like that and he’s going to referee a game next week.
“He (Hackett) is not doing his job properly and he needs to be assessed.
“I’m assessed as a manager, players are assessed, referees should be assessed properly by the right people. That performance today should not be accepted by our game.”
