I think that even though Real Madrid recruited a lot of players, they didn't spend much on their budget because they got Mbappe for free, at least 150 million euros he could spend on other players who certainly have good potential.
Several Madrid players have the ability to play in different positions, but Ancelotti cannot continue to do this considering the busy schedule next season, so regardless of how much money Madrid have to spend next season, buying defenders should be their main focus at this time, by having several reserve defenders, so at least Ancelotti no longer needs to shift the positions of several players in important matches later.
Maximizing players who don't play in their ideal positions will only be done in conditions that are quite urgent, just like what happened when Madrid lost many of its defenders last season, which requires Caarvajal, Tchouameni and Camavinga to play slightly different positions. But for now, they have to think about it because we must be aware that in the end Madrid must still add players especially for their defense and possibly also for the midfield even though it is not too urgent because the midfield is still quite complex in contrast to the defense which is currently still quite empty because of injured players like Alaba or players who leave like Nacho.
There are several players who are currently being targeted and rumors are flying about several players such as Davies and even Yoro.
The problem is that Madrid's situation is so unpredictable and they are so secretive when it comes to players that it becomes difficult for the media to detect in the end.
