Apart from that, money is indeed a problem because to this day salary issues have always been an obstacle to reaching an agreement with this player.
He is still very good in terms of performance but indeed in this kind of thing it is quite difficult when no one dares to bring him.
Another problem may be his selfish nature which is still visible during his time at PSG and this will obviously be another obstacle in my opinion.
Neymar is very likely to stay at PSG until his contract expires, because as you said apart from Neymar's very high salary, Neymar's selfish behavior is
a consideration for other clubs not to sign Neymar. We must remember that football is a game that relies on teamwork, so if there are players who
are selfish, it could damage the harmony of a team. That's why Chelsea, who have strong finances and desperately need a striker, were never interested
in signing Neymar. Chelsea only tried to bring in Lewandowski and Ronaldo, unfortunately Lewandowski was more interested in joining Barcelona.
While Tuchel did not like the game from Ronaldo. So in the end Chelsea decided to sign Aubameyang.
Now that player transfers are closed and it's clear that Neymar will not leave regardless of what PSG's attitude is now and it's very likely that as long as he doesn't want to lower his salary then it will probably be difficult for other clubs to sign this player.
As for Chelsea they now have an agreement with Aubameyang and although Auba's nature is still a little bit problematic with discipline but now he is a player who I think can take Chelsea in a better direction.
