The Football Association have charged Everton manager David Moyes and his assistant Steve Round with improper conduct following their post-match confrontation with referee Martin Atkinson at Goodison Park on Saturday.
Moyes was furious that, having seen his side dramatically pull level with two goals in injury-time after they had fallen 3-1 behind Manchester United, Atkinson then denied the Toffeemen the chance of a winner when he blew for full-time just as Phil Jagielka was about to fire at the visitors' goal.
As it turned out, United goalkeeper Edwin van der Sar saved the shot. But that did not appease Moyes or Round, who both raced on to the pitch at the final whistle to confront the match officials.
The FA have taken a dim view of Moyes' conduct and on Monday afternoon confirmed the Everton manager faces sanction under the organisation's new disciplinary procedures.
In a statement, the FA said: "Everton manager David Moyes and assistant manager Steve Round have both been charged with improper conduct.
"The charges relate to Moyes' and Round's conduct towards referee Martin Atkinson on the pitch following the final whistle at Everton's home match against Manchester United on September 11.
"Under the FA's new fast-track procedures, Moyes and Round have until Thursday, September 16, to respond to the charges and have both been offered a standard sanction of an £8,000 fine should they accept the charge.
"If either party denies the charge, the case will be heard by a regulatory commission within 10 working days."
