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.
This transfer season, PSG will lose several players it is clear that Messi, Mbappe and also Neymar, but these three players are PSG's core players, so it will be difficult for the club if they do not get replacements the same for all three players.
But are you sure this will be a bad start for PSG because they have lost their best players and only got poor substitutes?
Even though this is still a rumor but most of us believe that it will happen in the future.
