The bad news for Ahl Hilal is about Neymar and it seems he is still injured and there is a chance for this player to be absent for a few days in Al Hilal which can have a negative effect on this team however after Neymar join Al Hilal the fans were happy to see this superstar player in their teams and there was a positive atmosphere in the teams, also I think Neymar can have a player like Aleksandar Mitrović as forwards for Al Hilal which can make this team to have very strong forward for this season.
It is not worse news from Neymar for Al Hilal because he will be older and more sensitive with injuries. He will be like Bale after his 30s and Neymar is very unprofessional with his lifestyle which can make his body more sensitive with injuries.
The transfer to Saudi Arabia where is abundant of entertainment services will give Neymar more chances to enjoy his life. In return he will less focus on football and more injuries, less appearances, worse performance will come with time. Ah Hilal did not sign a long contract with Neymar and perhaps they will wait the first contract expires before considering to sign a new one with Neymar.
