Yes, he has to accept it, because no club is interested in recruiting players who are often injured, moreover him price is also very expensive. If Neymar stays at PSG he has to prove to the world that he still deserves to play in Europa, especially if PSG gets the UCL Trophy, this achievement will not be forgotten by fans PSG. But unfortunately many PSG fans are disappointed with Neymar, especially with the current hot scandal in various media.
Players who are frequently injured will only harm the team because they cannot play to strengthen the team for quite a long time.
That is why it is very rare for players who often experience injuries to be targeted by big clubs.
I just can't believe that Neymar will still play for PSG next season and surely sooner or later PSG will find a replacement for Neymar.
