Wenger has now been charged with misconduct for his post-match behaviour.
An FA statement read: “Arsenal manager Arsene Wenger has been charged following the West Bromwich Albion game on Sunday [31/12/17].
“It is alleged his language and/or behaviour in the match officials’ changing room after the game was abusive and/or improper and/or questioned the integrity of the match referee.
“He has until 6pm on Friday [05/01/18] to respond.”
Wenger was charged with misconduct in January 27 for pushing and shouting at match official Anthony Taylor during a game with Burnley.
The Arsenal boss was slapped with a four-game ban for misconduct.
Now, having been charged with the same offence, Wenger could be banned from entering the stadium for Arsenal’s upcoming games.
On December 31, Wenger and Co looked set to clinch all three points, before Chambers was adjudged to have handled a Gibbs’ ball in the box.
