The new season, which begins on August 12th, will have only 34 matchdays after the top flight was trimmed from 20 teams to 18, with only two clubs promoted from the second tier while four Ligue 1 sides went down.
Lens finished just one point behind PSG and will begin their new campaign at Brest.
PSG's schedule does not get any easier as they take on arch-rivals Marseille on matchday six on September 24th in 'Le Classique'.
PSG sealed their 11th Ligue 1 title last season amid turmoil at the club after they were knocked out of the Champions League in the last-16.
After the final game of the Ligue 1 season between Girondins de Bordeaux and Rodez was abandoned following a fan's assault on goalscorer Lucas Buades, Rodez were handed the victory by governing body LFP earlier this month.
The decision ensured that Rodez remained in Ligue 2, with Annecy being relegated as a result. Annecy had tried and failed to convince the LFP to make Ligue 2 a 21-club competition.
However, Annecy then stated that since the DNCG, the entity that controls the clubs' finances, had announced the administrative relegation of Sochaux, a spot was open for Annecy to stay in Ligue 2.
But Sochaux, who are scheduled to start their season at Troyes, said they will be appealing the decision.
