It’s called profit and sustainability, but the way football has gone with the money available to and pumped in to the top clubs makes the idea of sustainability a joke. It is not sustainable for a club to have to sell at least one top player per year and still fall foul even if their net transfer dealings are a profit. Or, to have to sell their homegrown players in order to meet PSR.
Financial Sustainability, maybe, but I doubt it.
Football sustainability, not a chance!
The whole thing is a mess!
