I'm conflicted on Bournemouth, because on the one hand it's great that they have been able to come from where they were to be realistic challengers for European football - without the ability of clubs to do that English football would be severely diminished. Unfortunately no-one can do that withoutthe largesse of some billionaire nowadays, but that's not exclusive to Bournemouth or their fault.
On the other hand, it isn't right that they have been able to get away with spending hundreds of millions on players without doing anything about the non-league standard shit tip they play at. They have the smallest ground in the top two divisions, and even their only competitor for that title in Luton have pretty much used the money they got from their one year in the PL to get spades in the ground on a new stadium. Bournemouth have had 10 years now on and off to get it sorted, it's not fair to other clubs who have spent 10's if not 100's of millions getting their grounds up to scratch.
