I just don’t see how
Barcelona are spending more than 100 (perhaps 150m ) million Euros (Lewa, Raphina?, Kounde) yet don’t have enough cash to register their free transfers.
They can't register their free transfers because of the wage cap based on a club's income, not because of whether they could afford them. Messi wasn't allowed to just play for free, La Liga rules state that a contract has to be a minimum of 50% of the previous contract, hence why they couldn't offer it.
