Wow im sorry to hear that. Definitely theres no return for him now. Is well documented in the books that fonding your mother will get you sick to the bones.
Injuries are only issues if they consistently appear in the same area. The thing that concerns me is the fact he had had a few foot injuries although I am not sure if it was the same foot and the same part of the foot.
The idea that alcohol had anything to do with for injuries is absurd. If he drinks a lot of alcohol it would affect his performance more than anything else.
The one thing I will add about Neymar who in my opinion is when fit easily within the top 5 players in the world (and still a higher level than Dybala)...... Is that when PSG bought him... His global appeal and popularity was extremely high. These days and especially after his antics at the last world cup and rape allegations etc.... His image had gone down a lot.... That should affect his commercial appeal which is used to in part justify his cost.
