Let Wenger have his fun. He probably fancies things this year and he always used to make these types of snappy comments. In the recent years he has been more repressed because everyone (including Arsenal fans) have been annoyed when he blames a bad refereeing performance or a bad pitch, but he always used to do be more bullish even in his more successful years.
It's not as if his comments are going to make any difference anyway. Hansen will just gingerly laugh it off and carry on - MOTD wouldn't want this in the public eye too much.
