I am sure Neymar leaving for Santos must be making Al Hilal fans happy to be fair. He got there when they were already good, and he got injured and didn't play, took their money, and now leaving. This doesn't really feel like it's fair, but at the same time they should be getting rid of him one way or another. I sure hope that he doesn't get any money from Al Hilal for leaving neither, because it is really unfair if he ever does that.
I am glad that Neymar fixed whatever legal issues he had in Brazil, I remember he had some issues with his agent or whatever about some finances and he was considered as "criminal" for a while, but obviously whatever it was, he must have fixed it if he is considering to go back to Santos now.
Neymar at Al-Hilal was a disappointment. He was very well received, well treated, well paid, and what did he bring back to the club? Absolutely. He only had a little marketing, but in terms of sporting terms he didn't add anything. He just received his dollars and nothing more. For me, Neymar is going to make the second biggest mistake of his career. The first was leaving Barcelona for PSG, and now he's going to Santos. The Santos team is horrible. They were playing in the second division of the Brazilian championship. They have no structure, no competitive team, no money... Neymar made a terrible choice.
