The rank hypocrisy here is all too typical of these people. They spend years calling Wenger every foul name under the sun, abusing him while he's trying to do his work, describing him as 'senile', 'incompetent' or organising marches against him or banners behind aeroplanes on high-profile occasions that do nothing but damage the reputation of the club and make us a laughing stock and cannot but undermine the performance of the team and think that's fine.
But Wenger points out in the mildest terms the negative impact such behaviour has had and these people are clutching their pearls and accusing him of behaving badly. Scum.
