The offer Real Madrid received for Vinicius Junior from Saudi Pro League clubs is tempting, and if Real Madrid decides to let Vinicius Junior move to the Saudi Pro League, the money they will realize from the Vinicius deal will help them sign a lot of players from different clubs, but I think Real Madrid isn't yet ready to sell Vinicius Junior, and Vinicius Junior won't want to move to the Saudi Pro League because he still wants to play for Real Madrid and have a chance of winning personal awards like the Ballon d'Or Award, so any possible deal for Vinicius Junior to move to the Saudi Pro League won't happen this season.
Vincius is an incredible player, smart, clinical, and decisive. Real Madrid wont want to lose a precious gem at his stage they are trying to rebuild the team to what it was in the past. We saw how they lost the La Liga to Barcelona, lost 4 matches against Barcelona and also were eliminated in the Club World Cup by PSG. That alone is enough reason why Xavi Alonso can never let Vinicius go, so far he is one of the remarkable and experienced player in the squad, so until the squad sits well with him, Vinicius still remains.
Agbamoni you are right, vinicius Junior is a very good player with a lot of skills and experience is impossible for real Madrid to let him go this year useless they are ready to experience more lost and failure, if they should decide to let vinicius Junior go a lot of big clubs will come for him and will pay any amount of money just to make sure they buy him because they know how good he is, vinicius Junior is still a very young player so real Madrid can't do that so they will keep him, vinicius Junior, Jude Bellingham and kylian mbappe are real Madrid most important players right now and they can't afford to lose any of them now.
However vinicius Junior has not been performing as he use to, I really don't know what the problem may be, could it be the injury he went, but if vinicius Junior, Jude Bellingham and kylian mbappe can co-operate very well they will be unstoppable, however let's see how strong or weak real Madrid will be next season.
