Arsenal boss Arsene Wenger is in hot water with the FA after he confronted referee Mike Dean and his officials after Sunday's draw at The Hawthorns.
The Frenchman was left frustrated after a controversial penalty earned the hosts a late equaliser which was "difficult to accept."
A statement from the FA read: "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."
The Gunners boss has until 6pm on Friday [05/01/18] to respond to the charge.
