The Frenchman was angry after referee Mike Dean gave the Baggies a last-minute penalty, which they scored.

It is alleged the 68-year-old's conduct in the match officials' changing room was abusive and that he questioned the integrity of the referee.

Wenger has until 18:00 GMT on Friday to respond to the charge.

Last January, Wenger was given a four-match touchline ban by the FA after being found guilty of misconduct after an incident with fourth official Anthony Taylor during a league game against Burnley.
