The spanish league rules that might prohibit a club now 1.7b in debt, unable to pay its current staff,players and contractors, and 40% over its wage cap commiting to crazy cintract for the world's best player and paying it off in the future. Those rules? They are lucky to be this in the clear to do what they are doing as it is, imo.
I agree, this is real knife edge stuff from Barca at the moment
