Everything has an end, and no footballer stays forever. One day, Thibaut Courtois will leave Real Madrid too. It may not happen this season or the next, but that day is getting closer. And when it finally comes, replacing arguably the greatest goalkeeper in Real Madrid's history will be one of the hardest decisions the club has to make.
For years, most Real Madrid fans believed the plan was simple. One day, Andriy Lunin would replace Thibaut Courtois. It felt like the perfect succession. But after the 2025/26 season, that belief is no longer as strong as it once was.
Lunin barely featured in La Liga, and after spending six years at the club, he has made only 74 appearances in all competitions. For a goalkeeper expected to inherit one of the biggest jobs in football, that simply is not enough. On top of that, his recent performances in Madrid's last three matches have not been convincing either.
Now Real Madrid face an important decision. Courtois is still one of the best goalkeepers in the world, but he is entering the final years of his career. Madrid cannot just wait and hope everything works out. If they decide to prepare for the future, these are the goalkeepers I believe deserve to be in the conversation.
The first name is Diogo Costa. The Porto goalkeeper has already shown he can perform at the highest level for both club and country. Whenever Portugal need him in big matches, he usually delivers. His reflexes are outstanding, he stays calm under pressure, commands his penalty area with confidence, and is excellent with the ball at his feet. He is also one of the best penalty-saving goalkeepers in Europe, a quality that can decide the biggest games. While his Champions League performances have not always matched his domestic form, his displays for Portugal prove he can handle pressure. For me, he is one of the strongest candidates if Madrid decide to invest in a new goalkeeper.
Then there is Bart Verbruggen. He might actually have the highest ceiling of all the realistic options. The Brighton goalkeeper is everything you expect from a modern keeper. He is calm with the ball, confident when building from the back, and his passing range would fit perfectly into Real Madrid's style. At just 23 years old, he is already the Netherlands' first-choice goalkeeper, which says a lot about his potential. The only concern is that he is still unproven at the very highest level. He has never been involved in a title race where every point matters and has not yet experienced the pressure of deep Champions League runs. He could become the best goalkeeper on this list, but replacing a legend like Courtois is a huge responsibility, and Madrid rarely gamble on potential alone.
Marco Carnesecchi is my personal favourite. He has everything I like in a goalkeeper. He is an excellent shot-stopper, stays calm in one-on-one situations, dominates his penalty area, and rarely makes unnecessary mistakes. His consistency has been one of the biggest reasons behind Atalanta's success. However, I do not think Real Madrid will seriously push for him. Italian goalkeepers rarely leave Serie A, especially when they are already playing for a top Italian club. Many prefer to stay in Italy, where the football culture and tactical style suit them. On top of that, Atalanta are never easy to negotiate with, and Madrid may not want to spend months chasing a deal that has little chance of happening. I truly believe he has the quality to succeed at the Bernabéu, but this transfer feels unlikely.
Guillaume Restes is the youngest name on this list and perhaps the biggest long-term project. He already shows maturity beyond his age, has excellent reflexes, and reads the game very well. It is easy to understand why so many top European clubs are keeping an eye on him. But signing him now would almost create the same situation Madrid already have with Lunin. He would still need time, patience, and regular football before becoming ready for the pressure of starting every week at Real Madrid. His future is very bright, but he is not the immediate answer.
Mile Svilar has quietly become one of the best goalkeepers in Europe this season. His shot-stopping has been outstanding, his positioning is excellent, and he has rescued Roma countless times with important saves. He looks mature, confident, and reliable. The only small concern is his distribution. He is comfortable with the ball, but his long passing is not quite at the same level as some of the other goalkeepers on this list. At a club like Real Madrid, where goalkeepers are expected to start attacks as well as stop them, that weakness becomes more noticeable. Even so, based on current form alone, he deserves to be part of this discussion.
Another goalkeeper who deserves a mention is Unai Simón. He has already proven himself on the biggest international stage. He played a huge role in Spain's UEFA Euro triumph and was also their first-choice goalkeeper at the World Cup. He is experienced, composed under pressure, and knows what it takes to win. The biggest problem is his price. Athletic Club are one of the toughest clubs to negotiate with, and signing one of Spain's best goalkeepers would almost certainly cost far more than any other realistic option. Even though he is an excellent goalkeeper, the financial side of the deal could make it very difficult.
When everything is considered, there is no perfect replacement for Thibaut Courtois. Every goalkeeper brings different strengths and different risks. Diogo Costa offers experience, leadership, and international quality. Bart Verbruggen may have the highest potential, but he still needs to prove himself at the very highest level. Marco Carnesecchi has every quality needed to succeed, yet leaving Italy seems unlikely. Unai Simón is already a proven winner, but his transfer fee could be enormous. Guillaume Restes is a brilliant talent for the future rather than an immediate solution, while Mile Svilar is enjoying an incredible season and continues to improve.
If Real Madrid decide to sign a new goalkeeper, they should not rush the decision. Replacing Thibaut Courtois is one of the biggest choices the club will make in the coming years. Talent alone is not enough. They need someone who can live with the pressure of wearing the white shirt, playing in front of 80,000 fans at the Santiago Bernabéu, and delivering on Champions League nights
If I had to choose one goalkeeper today, I would go with Unai Simón. He has already proven himself on the biggest stages with Spain, winning the UEFA Euro and performing at the World Cup. He has the experience, mentality, and leadership needed to handle the pressure that comes with being Real Madrid's number one. Yes, his transfer fee would probably be the highest on this list, but sometimes paying more for a proven goalkeeper is worth it.
That said, Real Madrid should stay calm and evaluate every option carefully. This is not a decision that should be rushed. Finding Courtois' successor is about much more than signing a talented goalkeeper. It is about choosing the right player to protect Real Madrid's goal for the next years....
