It would do him no good, as no one would want to buy him.
I still think there is more to that ruling. The player has to apply to FIFA to be able to buy out their contract and stuff.
Why not?
The rule exists and can be applied. Applying to FIFA is a formal procedure. If the requirements of the rule are satisfied, then there is no problem. The problem rather is that it takes several months. But when a great player can be signed in this way, this is hardly a big problem.
