This was technically a free transfer for PSG because Messi was a free agent after his old deal - which contained a €700m ($1.1b) buyout clause - had expired. But the French club has also reportedly paid him a sign-on fee of €30m ($47m),enough to dwarf most transfer fees in football.
These are the sort of numbers that after years upon years of undisciplined and unregulated spending are threatening to send Barcelona broke,and which an increasingly small number of clubs - backed by either oligarchs or nation-states - can afford to even contemplate.
