Even though in this case his contract with PSG still exists but seeing the tension that always occurs, not only rumors with Mbappe but with the club owner there, in fact, in my opinion, in this case, the chance for Neymar is also a little small to stay, except if no one dares to take him then it's possible he still survives and will leave when his contract expires.
Now Neymar's problem is of course increasing with the conditions where fanatical fans from PSG even tend to be condescending and immature with their attitude which makes this uncomfortable I think.
It's still possible now but if any club is willing to pay PSG what they want in this case I still don't think they would hesitate to let Neymar go.
because indeed Neymar is no longer comfortable at PSG. I don't think there is any reason not to leave PSG in this transfer market. what's more, it has been rumored there has been some interest from Premier League clubs and also from the Saudi League.
but everything also depends on Neymar, because the surprising decision also came from Messi who finally dismissed all the rumors by joining the American team.
There has to be a team that really wants him first but it's speculation around Newcastle and even Arab teams that want him to still be around now so this is still a possibility.
Now there is another speculation after Al Hilal failed with Messi they changed course with Neymar now. there is even news that they are ready to pour out big funds and lure Neymar with a salary equal to Ronaldo.
If these rumors are true I feel very sure that he will leave very big, as you said Neymar will not get comfort at PSG with all kinds of conflicts that exist with officials and fans. but if indeed this is just a rumor that is exaggerated I think he will stay for one more season with a definite insult because leaving there must also be a club to go to.
