If he can recover that would be great, but so far it seems that he doesn't want to play football anymore and it's nothing more than a money making endeavour for him. And with this approach, as we know, nothing good usually happens, that's all. It will probably be his last club in his career and he will not play there for more than two seasons.
It would certainly be great if Neymar could fully recover, considering that many people still hope he can play in the upcoming 2026 World Cup. In my opinion, there could be many reasons behind Neymar return to Santos, perhaps because Neymar wants to be closer to his family, in addition to the injury that has prevented him from playing for Al Hilal until now. So far, there has been no official news stating that the two clubs have reached an agreement, what is clear is that Neymar must be willing to take a pay cut if he does leave Al Hilal. With his physically injury prone condition, there is a possibility that Santos will be the last club in his football career.
It's obvious that Neymar does not long stay in football any longer,I think by 2026 will be his last performing in football carers, so for now he sustain injury and I'm thinking that is using the injury to delay his time so that he can recover fully to participate well in world 2026, I think the analysis you tender concerning him going to the club he started with at Santos is right, he is planing to return home, because I have come across of such in a newspaper before, so I believe their's fact on your discussion.
