Every time we have one of these moments where the club is getting a lot of attention, parts of the fanbase mobilise into policing who is and who isn't part of the fanbase.
It's a pretty miserable trait and I think like so many of these nasty behaviours says more about their own feelings of inadequacy than those of the people they're attacking.
Ultimately, what has got us to record attendances at Wembley, regular sell outs at home is people coming back to the club who were not attending previously. Their return has been part of the story. Even if it it wasn't, policing who is and who isn't a real fan is just a waste of energy.
