da realsbet： Arsenal manager Arsene Wenger has slammed his UEFA improper conduct charge following their 3-1 loss to Barcelona in the Champions League.The Londoners were level 1-1 with the Catalan giants, and ahead 3-2 on aggregate at the Camp Nou on Wednesday when star Robin van Persie was given a second yellow card for time-wasting following an offside flag.The French boss was furious with the decision, approaching referee Massimo Busacca after Arsenal were eventually ousted from the competition courtesy of a 3-1 loss following van Persie’s sending off.Wenger has followed up his outburst by denying he was at fault to protest the decision.”I deny completely any charge. I do not understand where that comes from,” he said.”It is a shame for me that the referee took the decision to send Robin van Persie off. It was the wrong decision.””The first leg was a fantastic advert for football and the second game has been destroyed. People now will only remember the sending off.””It would be good for UEFA to show some humility, to apologise for what has happened, not charge people who have done nothing wrong.”Midfielder Samir Nasri has also been charged by the European football body for inappropriate behaviour at the final whistle, with punishments yet to be decided upon for the pair.
