The reason Real Madrid borrowed Kepa Arrizabalaga was not because of financial conditions, they refrained from spending money at an unplanned post. Real Madrid has spent a lot of money in the transfer market, one of which was to bring in Bellingham for a transfer fee of € 103 million.
Real Madrid still has cash that can be used to bring in new players, the funds that have been prepared are not to bring in new goalkeepers, but to look for quality strikers if needed.
Courtois will return soon after undergoing treatment, Ancelotti can still rely on the goalkeeper he currently has. Real Madrid prefers to save their money in order to bring in Mbappe because Perez really wants him to join the Real Madrid squad.
Yes, it's true that Kepa's presence is not for the long term because Courtois has been injured for quite a while so Real Madrid must move quickly to find a replacement for the goalkeeper for this season, Real Madrid are indeed preparing money to look for player number 9 to replace Karim Benzema after being left by Benzema to al ittihad, kylian mbappe is the one who is considered suitable to replace his position, but it seems like real madrid is not easy to get him. Because Kylian Mbappe has just renewed his contract with PSG until 2025. If Real Madrid are still unable to sign him next season, I think Kylian Mbappe will stay at PSG or anchor at another club. The rumor about Kylian Mbappe to Real Madrid has made it the longest rumor ever in the world of football, starting from 2019 until now it is still unfinished. Can real madrid bring in player number 9 who has the same ability as karim benzema?
Even when you consider Kepa will be short term, I do not think that it makes sense to get him. Real Madrid is a serious club and they like to play with a good discipline whereas Kepa is a weird one at that. We all remember him not wanting to subout when the manager requested it, something like that would make you get cut from the team right there on the field, they would not be able to escort you out with security, but as soon as the game is over you will be hearing that you are fired.
This type of goalkeeper is not good for Real, they should have gone with De Gea just like everyone told them to, it was the right thing to do and the right move and for some reason they declined to do it, no idea why.
