The decision he made today can't be overlooked. He's made it worse by not holding his hands up. Admitting he's wrong is not something he usually does but he needed to do it today because for a moment all the fans, the players, the media, everyone was just thinking WTF? And Wenger was 100% alone (apart from the board of course who probably thought it was genius to hook Ox, save on a win bonus by turning it into a loss). It's all downhill for Wenger now. He's made himself look a fool and then tried to say everyone else is the fool. He could have even changed his mind when the boos started ringing out (what the fuck did he expect) and grabbed the 4th official and strangled him, or short of that said 15 was a mistake and fucking obviously change it to 14. Nobody could have argued with that.
