Paris Saint-Germain clinched the French league title without kicking a ball as second-place Lille could only draw 0-0 at Toulouse on Sunday.
Lille had to win to have any chance of catching PSG, but PSG is now 16 points ahead of its only rival with five matches left after this weekend.
After failing to clinch the title in the past three matches, drawing one and losing two, PSG can celebrate the eighth title in its history ahead of its home game against Monaco later Sunday.
It is PSG's sixth title in the last seven seasons, with only Monaco in 2017 breaking PSG's dominance.
Although the title was long expected from a side scoring 92 goals in 32 games so far, it took longer than it should have.
PSG could have won it three games ago, but drew 2-2 at home to Strasbourg when a win would have clinched it.
Then PSG needed a draw at Lille last Sunday, only to lose 5-1 in the club's heaviest defeat since Qatari investors QSI took charge of the club in June 2011.
A win away to Nantes would have sufficed, too, on Wednesday night only for PSG to lose 3-2 .
The 10 goals conceded in those three games made for PSG's worst defensive record during a three-game spell since 1985.
Also Sunday, striker Kalifa Coulibaly scored twice as 13th-place Nantes beat 17th-place Amiens 3-2.
Later, Saint-Etienne needed a draw at Reims to move above Marseille and into fourth place.
