I think he did / does, if Madrid can’t afford him though what then? Can’t see PSG letting him run his contract down so does he extend there or does he rethink his options ?
I can't imagine a club like Madrid haven't budgeted for this.
In addition, they could easily go to banks and take loans to cover some of it, and the revenue a player of his caliber would generate, they would have no problem paying it back.
