The problem with having a half empty ground in the hope that the penny will drop will backfire on the fans - the media will just say we are fickle, and the club don't really care because the TV deal means the armchair fan is more important to them than us mugs who show up every week. We need to find a way to publicise just how shocking Lambert's record is - worst home record in our history, record defeats without scoring, the least number of goals scored in the entire football pyramid, routinely getting dumped out of cup competitions to lower league sides, negative tactics etc etc. Someone had a good bedsheet message at Burnley yesterday - 'the stats don't lie'. Highlighting Lambert's failings with banners like that will work better than just not turning up.
If we lose to Palace and he still doesn't sack him, boycott the Leicester game or turn up and leave a card on your seat stating the obvious,then go home before the match starts.Westley ( so obviously planted by the club) can then sit there on his own.
