The Arsenal boss remains furious that the controversial Italian striker\'s challenge on his midfielder went unpunished due to a loophole in the authority\'s rules.Arsenal manager Arsene Wenger has blasted the Football Association after Manchester City striker Mario Balotelli escaped any further punishment for his studs-up challenge on Alex Song.The FA ruled that because one of referee Martin Atkinson\'s assistants had witnessed the incident, that retrospective punishment went against their code of practice and would undermine the official in question\'s authority, something Wenger vehemently disagrees with.\"The FA should change this rule,\" he told The Daily Express.\"I think we should have an exceptional committee of ethics to get over this issue.\"The global situation does not make sense.\"For people who love football, it is difficult to understand.\" The Frenchman went on to cite the incident involving QPR\'s Shaun Derry, who was handed a one-match ban and had his subsequent appeal turned down, after seeing red against Manchester United for apparently fouling Ashley Young.Wenger insisted that the punishments currently being handed out simply do not match up to the crimes being perpetrated.He continued: \"If you put them together it looks absolutely unbelievable that one is suspended and the other isn\'t.\"
