The FL rules are limiting ambitous Championship Clubs ability to build teams to challenge for promotion, and then sustainability in the PL if they get promoted. Some already have transfer embargoes placed on them, others like Bournemouth I understand already risk penalties if they get relegated again. We are already in that situation - just not clear to me anyway whether our Owners clearance of most of the accounting loss liable to penalty from our last season in the Championship have saved us from penalty, or whether increasngly more likely with the silence on the issue, the subject is undergoing legal arbitration.
I think many PL Clubs are heavily reliant on owner generosity. Newcastle, Sunderland, Palace, Leicester, Liverpool, Southampton, Stoke all seem to be - harder really to think of any who aren't, Arsenal maybe.
