The Gunners boss was fuming after his side conceded a dramatic equaliser in the fifth minute of stoppage time at the Stadium of Light.
Wenger appeared to sarcastically pat Martin Atkinson on the back as Darren Bent’s goal came 15 seconds after the allotted four minutes, and was also critical in his post-match comments.
The Arsenal manager could accept the charge and a one-match touchline ban and £8,000 (€9,500) fine under the FA’s new fast-track disciplinary procedures.
A statement from the FA read: “Arsenal manager Arsene Wenger has been charged with using insulting and/or abusive language and behaviour amounting to improper conduct.
“The charges relate to Wenger’s conduct towards match officials at the conclusion of Arsenal’s match against Sunderland on September 18.’’
Wenger could not see why any additional time should have been played.
Speaking after the match the Arsenal manager lamented: “It was outside the four minutes.
“I know the referee can give more than four, it’s a minimum of four minutes, but in the four minutes nothing happened to justify the extension of the time.’’
Meanwhile Cesc Fabregas has allayed fears over his injured hamstring and expects to be back playing inside two weeks.
The Arsenal skipper sustained the knock during a 1-1 draw away at Sunderland on Saturday.
Fabregas said last night he expects to be back in action in two weeks time.
“Good news on my injury. I have some fluid but nothing bad in the muscle.
“I hope I can be playing in two weeks,’’ Fabregas said on his twitter page.
Wenger will again rotate his Arsenal squad for the Carling Cup third round clash at north London rivals Tottenham tonight.
Goalkeeper Lukasz Fabianski, Johan Djourou, Emmanuel Eboue and Kieran Gibbs are all set to feature having been unused substitutes at Sunderland, but youngsters Jay Emmanuel-Thomas, Benik Afobe, Chuks Aneke and Henri Lansbury are also likely to be involved.
