The very case when the dream turned out to be more expensive than money, because in the long run it will be easier to become a sought-after player at Real Madrid, they have everything they need for that. It will be interesting to see Real Madrid's transfer market in general this season, they have few weaknesses in the squad, but the new coach is unlikely to think so and will bring in the players he wants.
Dean Huijsen did not waste the opportunity to join Real Madrid, even though he almost joined Chelsea, Liverpool and PSG were also interested in signing him, but once Real Madrid came calling, he closed the door on the club even though he was offered a higher salary than he received at Real Madrid.
His contract with Madrid will start on June 1, 2025 and will officially play in the Club World Cup, this deal also makes Huijsen the most expensive defender in Real Madrid history.

Am not that surprised that real madrid will be investing so much on him actually because in as much as he is still very young, he is quite experience in his short career already, and secondly he is a Spanish international, so why wouldn't they rate their own that high?
Am not being sentimental here actually but the hype surrounding his potential impact at real Madrid might even make him flop if care is not taken.
Though he is actually good, but the level at which he is being hyped is actually not good because it might be an add pressure to him, because the fans will start seeing him on the same level as rudiger which is not proper for his development.
Though nothing is certain if he is going to perform very well at real Madrid the way he did at Bournemouth but am quite hopeful that he can replicate his Bournemouth form at real Madrid because expectations at Bournemouth is nothing comparing to real madrid, so the level of pressure will be totally different.
