The injury is a big blow to Real Madrid. Thibaut Courtois struggled for a while when he arrived at Real Madrid but he has cemented his place as the club's number one goalkeeper. The ACL fracture looks like a lengthy injury, thus Andriy Lunin and Luis Lopez cannot be relied upon to be in charge on goal because of their less game time and experience, a more suitable alternative is needed.
This is not just the way that Real Madrid were expecting to enter this season, they did not win the La Liga last season, they would have been hoping to start very well this season and give Barcelona who are the current defending champions some problem. Maybe Real Madrid will consider Ramsdale from Arsenal and try to bring him to Real Madrid since Arsenal have just contracted the service of a new goalkeeper from Brentford that will now share playing time with him. Ramsdale is still a good Goalkeeper, he can fill the spot of Courtois until he returns.
