You seem to be missing the point.
Frenkie stays, he gets his money and Barca have a massive financial problem and cannot register players. In this scenario only the player wins, if you can call winning being stuck at a club where you are hated for stopping them from registering their new stars.
Frenkie leaves with a payoff, still gets his money and Barca resolve their issues. Now both sides win and can move on and Frenkie gets to play his preferred position at a club where he is wanted.
Now tell me which of the above is the most likely outcome?
