Yes, unfortunately it is. If Neymar doesn't have many injuries, maybe we will see him playing to his full optimal, as a striker and the most expensive player he should be able to give good results for PSG. By the way, if Luis Enrique becomes PSG new coach, Neymar is likely can stay in Paris. Because Enrique really understands the character of this striker, so I think there is still an opportunity for Neymar to show his great skills at PSG.
Even though PSG has planned to let Neymar go and there are already several clubs that are eyeing him, moreover Man United or Chelsea. but this is still a rumor. If it turns out that Enrique later changes his mind, he might reconsider. But in my opinion, PSG will still let Neymar go if there is a price agreement with another club. He had quite a small contribution during the last season in PSG although his transfer fee is very high, but he couldn't make it awesome during being in PSG.
The power of a club is absolute, but if later Enrique expects Neymar to stay at PSG, of course that will be a serious consideration for next season's competition. I think that even if there was no Neymar, PSG would still win the Ligue 1 title and they would still need new players to enter a more difficult competition, namely the champions league. At the moment PSG have not had many rumors regarding the players they will sign in the summer and I think they should do it soon because a team like Lens will be one of their competitors in Ligue 1 next season.
