I don't like seeing fans constantly jump on the best president the club had. If Laporta, the best president this club had, does not manage to make the model function, then for me it's even more indication the model is unsustainable. And the discussion about private ownership in FC Barcelona, at least partly, is a mere question of when not if.
I highly doubt the next president after Laporta is gonna have to deal with the mess Laporta took on in these 4 years. Net spent on squad at Championship levels in England, with every player registration being a legal battle and an exercise of imagination and rule loopholes chase.
