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.
Last season was a nightmare for Real Madrid because they lost all their matches to Barcelona. It may have never happened before that Real Madrid lost all their El Clasico matches in a season. Just like they lost the El Clasico match, they also failed to perform well in big tournaments like the Champions League, Club World Cup and other tournaments. The star players of the team, especially those who play in the strike position, cannot be blamed much for Madrid's poor performance because Real Madrid has been playing with a shaky defense line-up from the beginning. If Real Madrid really wants to change their performance and do well in all competitions next season, then they need to improve their defense position a lot. Maybe it is a lot of pressure for the manager, but the manager has to accept this pressure and make the team a top performing team again.
