They will, but if they manage to attract them again they'll soon want to get rid of them once the teams successful, and the circle continues.
I know I hark on sometimes about how scotland have transformed the atmosphere in their grounds but its a good way to compare because they had similiar things happening up there that we had here.
They have (for the most part) embraced the ultra groups that have formed. They've reduced prices for the younger fans. Enganged and talked to them. Knowing that these younger fans are the future.
Maybe we have enough fans that they can be treated in such a dismissive way and still get good attendances. I think we (and most english teams) do....this has been happening for 30 years and football attendances continue to grow.
