I don't see how them signing a dozen football stars changes anything, it's just an empty PR stunt. the football stars that go there lose 90% of their appeal and there's free room for new stars to blossom.
now if they actually used those funds to steal hundreds of people away from the excellent French academies, Barcelona, Real Madrid, Ajax, Arsenal, etc and try to build world class infrastructure and real football pyramid we'd have something to worry about, but they don't seem to be interested in building things.
