Not in a footballing sense, no, but I wasn't thinking about the geopolitical rivalry between Saudi Arabia and Qatar. If they don't have much a market for Neymar, though, I can't see them keeping him around just because Newcastle's the only potential suitor.
I just can't think of other clubs that'd want him. Barcelona are only bringing in older players as free agents, and they'll be focused on bringing Haaland in. Man. City won't touch him given how expensive he'll be. United might go after him only if they can afford it. Chelsea have other things to worry about at this time. The rest of the teams (Real Madrid, Bayern Munich, etc.) won't go for him for various reasons.
