Éder Militão is currently unable to contribute fully on the pitch, but when Real Madrid wants to bring in another new player to replace Éder Militão this seems too excessive. Maybe they can consider sticking with the players they have rather than having to buy more because it will cost them a lot of money. for new players again. At least Carlo Ancelotti must consider this carefully so that there are no problems regarding Real Madrid's finances in the future.
Ancelotti knows a player who is already unworthy of being defended and has to find a replacement to fill a vacancy in an unproductive player. And if you know the talent that Éder Militão has, he's actually worthy of being defended, not because Madrid doesn't want to waste a lot of money, but indeed he has a very reliable talent and Ancelotti does not want to make a big change on a perfect line of defense.
Madrid has always been heartfelt in the move to sell players or bring new players, because the legacy of this team has a reputation to keep on being cared for and always prioritizes the right players to have high productivity and the Éder Militão has all that. So there's no choice but to keep that reliable defender.
I would say that on the contrary, they are known as a team who rarely ever gets emotional about players, they sold Ronaldo off like he was some useless player, sure they got some good money for it, but they didn't care, or sold off Benzema just a year after his Ballon D'or level of playing. All in all, we could say that we are seeing Real Madrid not get emotionally attached to players all that often, maybe fans can, but not the team itself, not Perez.
This is why if they ever feel like Militao can't give them what they need from him? They will sell him right away, or bench him, and get some other player who would do a lot better. They are aware that they need to keep being at the top, because if they start losing, they won't recover that easily. Look at what happened to Barcelona, great for many years, made a couple mistakes and now they are in big trouble.
