In this season Real Madrid was a little bit unlucky because they lost their forward Karim Benzema and they couldn't hire any other player to fill his place and then their defender got injured hardly in the first weeks, also Thibaut Courtois got injured and Real Madrid knows he can't play for weeks, after that they hire another goalkeeper to fill his place in the next games.
When Kepa Arrizabalaga joined Real Madrid and they spent too much money on him, the fans of Real Madrid were worried about his performance but Arrizabalaga had a good performance in the previous trainings, also he attracted Anceloti's attention.

Kepa Arrizabalaga is a very good custodian who Chelsea typically uses to play their matches, so getting him to replace Courtois is a very good thing that Real Madrid did. I don't see anything wrong with Real Madrid buying him because I believe that if his performance is poor Chelsea will want Real Madrid to buy him directly rather than on a loan. Despite the fact that Real Madrid needs additional players to fill certain positions, such as the striker position, Real Madrid, in my opinion, does not lack defensive players because a player will fill the position, which is why I only highlighted the striker position.
Real Madrid, in my opinion, won't have too much trouble this season since they still have players, and those players will be regarded as the greatest in the La Liga because there isn't a single player in Real Madrid who isn't intelligent. and I think that even the stricker position that Real Madrid lacked won't be given to the team because I know that Rodrigo and Joselu can try playing in that spot, and even Bellingham can play the position if they are on the pitch. I also really like how Bellingham played in every position to boost the performance of the team.
