While Paris Saint-Germain have not yet mathematically clinched the Ligue 1 crown, they are already champions in Luis Enrique's eyes, with the head coach saying the title is "99.9%" theirs.

PSG beat Brest 1-0 on Sunday in their final home game of the season, with Desire Doue coming off the bench to score an 82nd-minute winner.

The victory restored their six-point advantage over Lens with two games remaining, and even though they face their nearest rivals in their penultimate fixture on Wednesday, a title turnaround looks highly improbable.

Lens would have to take maximum points while hoping PSG do not earn another point, and see a 15-goal swing go in their favour, to snatch the trophy.

The Opta supercomputer assigns PSG a 99.99% chance of retaining their crown for a fifth successive year, with Lens only pulling off a miraculous fightback in 0.01% of scenarios.

And Luis Enrique agrees with those percentages. 

"We are champions!" Luis Enrique said after full-time. "I can say it, can't I? It's 99.9% sure! And I think we deserve it. 

"We still have two matches to play, but we have a big advantage with the goal difference. Mathematically, we still need one more point, but I think we are champions. 

"That won't change how we approach next Wednesday's game, or Sunday's against Paris FC. 

"We will prepare these games one after the other, in order to arrive at the Champions League final on May 30 in the best possible form."

In the three-points-for-a-win era in Ligue 1 (since 1994-95), no leader with an advantage of more than one point with two games remaining has ever failed to win the title, let alone a six-point lead.

Against Lens, who cannot drop any lower than second, PSG could become the third team this century to officially win the Ligue 1 title against their eventual runners-up, after Lyon versus Lens in 2001-02 and PSG versus Monaco in 2017-18.

Doue's goal came on his 100th appearance for PSG in all competitions, and he now has 50 combined goals (29) and assists (21) for the club. 

At 20 years and 341 days old, he is the second-youngest player to reach this milestone for the club in the last 30 seasons, behind only Kylian Mbappe, who was 19 years and 291 days old at the time of his 50th goal involvement.

"It's arrived very quickly, but I'm delighted to celebrate my 100th match for Paris here," Doue told the club's website. 

"We still have two games to go in Ligue 1, but to win our last game at the Parc des Princes is great. 

"It's never easy. Every opposition team has good players and they always give 200% when they come here. 

"Tonight we played well. We were focused from start to finish, and we got the win. That's the most important thing."
