A victory or a draw. PSG will have to be able to glean this on Saturday afternoon against Angers so as not to ask questions, having to wait a few hours and keep an eye on the confrontation between Brest and Monaco hoping that players of the principality will not refuel. One point, only one, Saturday at the Parc des Princes would indeed do the case to mathematically validate the 13th coronation of Paris in the French championship.
Keeping your invincibility intact on the national scene would have allowed Paris to formalize its new coronation, it would not be a question of celebrating the event in stride. In any case not with great fanfare.
