Arsenal coach Arsene Wenger was charged with improper conduct by UEFA today following his criticism of match officials after his team's UEFA Champions League exit.

Wenger hit out at a referee following the 3-0 win over AC Milan yesterday, which was not quite enough to overturn the Italians' 4-0 lead from the first leg of their last-16 tie.

"UEFA has opened a disciplinary case against Arsenal manager Arsene Wenger for improper conduct in relation to last night's UEFA Champions League round of 16 second-leg match against AC Milan in London," said a UEFA statement.

The case will be dealt with by UEFA's Control and Disciplinary Body on 29 March.
