Arsenal lost the last-16 second-leg match 3-1 to go out 4-3
on aggregate and Wenger was furious at a second yellow card shown to striker
Robin van Persie in the 56th minute for kicking the ball after the whistle
sounded for an offside decision.
At that stage the score was 1-1 at the Nou Camp, with
Arsenal 3-2 ahead on aggregate.
Wenger remonstrated with Swiss referee Massimo Busacca after
the match, following him down the tunnel to continue speaking.
Van Persie claimed he had not heard the referee’s whistle
before blasting the ball wide. Wenger told a news conference the decision was
“embarrassing” and said UEFA representatives at the game had been shocked by
the decision.
Nasri has also been charged with improper conduct for his
comments to the referee after the match, while Van Persie could also be in
trouble after describing the decision as a joke, saying that Busacca had “been
bad all evening.”
Wenger was given a one-match ban for improper conduct in
2007 for showing dissent against a referee’s decision in a Champions League
match.
Wenger and Nasri will have their cases heard by the UEFA
Control and Disciplinary Body on March 17.
