From what I've read, Neymar bought a plot of land in a gated community in Rio de Janeiro, where he intends to build a mansion, so everything indicates that he will soon return to Brazil and the team he's been flirting with is Flamengo, which in theory is the only team in Brazil that can afford to pay Neymar's high salary.
But he is still good for the Brazilian team because currently they are having no big player who can do anything positive for them but due to long injuries things are not going as expected so Brazilian soccer future and Neymar both are hanging around with poor performance and struggling for the better days now we have to wait next World Cup qualifiers for having major updates about him.
Meanwhile, we must admit that the Brazilian National Team lost a player who was able to make a difference when Neymar was absent, this confirms that his role is very much needed. Indeed, Brazil does not lack talented players, but they do not have the same flying hours as Neymar, his experience and expertise are difficult to find in other players. The upcoming 2026 World Cup event will most likely be the last event for Neymar, and for now it seems that he will stay in Saudi until his contract ends.
I think the biggest problem is not that he is in Saudi Arabia, the problem is that he has to improve quickly to be in optimal conditions to Compete for his country, Brazil is not doing very well in football right now. I think the problem is a lack of leadership. They need a more determined coach to get good results, because they haven't done well in the qualifiers for the next World Cup and that's something that has affected them a lot. They are much better off with Ney, and as soon as he is well, even if he lives on the other side of the world, he should go to help his Team.
