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.
Neymar Jr could be 33 years old after one week and his injury prone history keep him away from his best after leaving Barcelona for PSG and his arrival at Al Hilal were not profitable for them as well mean now things are getting worst after every day for him in soccer. His contract is for 6 months with option of 1 years extension which is good because now if he wants to keep himself fit until FIFA World Cup this is right decision to settle here and work on his fitness and also performance.
Most feel he is currently the best production of Brazilian soccer but sadly due to his off field activities and injuries he had never been able to do anything right for his career which is huge disappointment but now it's last chance for him if he is able to do anything positive for his country he needs to work on this because after these things could be never came back for his best.
