Part of the £198m that psg paid, cover his loyalty bonuses mate. If you take the bonus payments out, the transfer fee is lower. Agents have done this for years.
That's you saying that, not what the court said.
A signing on fee that Zin mentions, I can see, if that is spread over the contract it makes sense the player gets the remainder of that when he leaves. But as I understand it a transfer request only forsakes the loyalty bonus. And that, with other performance bonuses, stop anyway when his contract ends with his move elsewhere.
