About Neymar's being signed by Al-Hilal I think that he has done the right thing for himself. Because it was clear that he had no future at PSG from now on. He has been struggling with injury problems for a long time. He missed so many matches last season for example. PSG also wanted this transfer to happen.
Neymar is going to earn 300 million dollars for 2 years and it can go up to 400 million as well. He can just earn lots of money there.
He earns everything from al hilal. Neymar was not just getting money, but he is also getting luxury life from the saudi club. It's hard to imagine neymar denying such an offer. It sounds nonsense as this guy really care about money instead of his passion. He has got many trophies and why's next? He needs to enjoy his life after he spent so many years in the football. Neymar is gonna play with so many prominent names in al hilal.
He is making the right decision. I don't know the possibility of him returning to the european competition. He may stay there for many years.
