Any team will prefer younger players, but you understand that Ancelotti does not have time now to try how young players can enter the game, he now needs players who can immediately enter the game because the season is already in full swing, and further losses can only worsen Real's situation.
In the last rounds they have slightly reduced the gap with Barcelona, but to continue to pursue them they need a reliable defense. Real recently reported that they do not have money for new transfers, so they wanted to sell several players, so before looking for replacements for injured players, they need to find money for this.
Ancelotti has proven that he prefers to launch young players and combine them with senior players in the Real Madrid team and in the last few seasons he has done this quite successfully even though the situation is a little different now, because they need players to fill the void left by Real Madrid's main players who are injured but I don't think recruiting young players is wrong, in fact it can be an investment in the future.
Real Madrid is a financially strong team so I think there is no doubt about that, they only need a few players in the defensive line and Ancelotti has confirmed that they will recruit in the January transfer window.
With the current conditions, of course Real Madrid management will support that, because they will definitely try harder to be able to defend the La Liga title this season.
Young players are not only good for business, but they can also still make a contribution, and they might even become one of the key players. Martin Odegaard is one such example, and he left Madrid not because he played badly there, but more because Madrid had too many star players at that time, so Odegaard didn't get many opportunities to be on the pitch.
It would be better to have young players alongside older or star players, so he can be a backup and learn many things that will make him improve more. But the situation currently facing Madrid is a different case, and demands more signing of experienced players rather than young players.
