LONDON (AP) — Arsenal manager Arsene Wenger has been charged by the English Football Association for his actions inside the match officials' changing room after a Premier League game.

The FA says Wenger's language and behavior following Arsenal's 1-1 draw at West Bromwich Albion on Sunday was "abusive and/or improper and/or questioned the integrity of the match referee."

Wenger was unhappy at the awarding of a late penalty against his team for handball by Calum Chambers. West Brom converted the penalty in the 89th minute for the equalizer.

Wenger said the decision was "difficult to accept" and that referees "do not work enough."

The FA said Tuesday that Wenger has until Friday to respond to the charge.
