You're welcome
Real Madrid put clauses when they sold players that were essentially if X player is sold to a Spanish club within the next four years you have to pay us 50m for it.
Basically putting off clubs from re-selling players to Barca I guess as I'd imagine Real Madrid would waive that clause if one of their ex-players were sold to Getafe or some shit.
But I brought it up as to point out that once the employer employee relationship is terminated does not mean that everything written up in contract goes void.
I am probably still wrong about this.
