Real Madrid is always alert to every move in the market. Although Xabi Alonso already has an almost complete squad, at Bernabéu they aren't letting their guard down.
Defense remains a priority. That's why they're looking for a replacement for Antonio Rüdiger, a player who's given a lot but is going through a difficult time.
Rüdiger's drop after the injury
Antonio Rüdiger, European champion with Madrid, hasn't been performing at the desired level since his meniscus surgery in April. The German has struggled to recover his best form.
His contract ends in 2026, but the club wants to prepare for the future calmly. That's why they're already thinking about a long-term replacement. The idea isn't to rush, but to look for young talent that can grow within the team.

Oscar Naasei Opong, the surprise bet
This is where a name few expected comes into play: Oscar Naasei Opong. This young 20-year-old center-back plays for Granada and has attracted Madrid's interest.
This wouldn't be an immediate signing for the first team, but for Castilla, where he could adapt and grow. Naasei has alternated between the reserve team and Granada's first team, playing 13 matches with the former and 7 with the latter.
His arrival at Castilla, now managed by Álvaro Arbeloa, would fit into the club's strategy of strengthening the defense with young prospects. In addition, the reserve team aims to be promoted to Segunda División, a goal that would boost Naasei's development. The idea is that, in the not-too-distant future, he could be Rüdiger's natural successor.
An active market in Valdebebas
This move wouldn't be the first Castilla has made this summer. They've signed Rachad Fettal to replace Gonzalo García, who scored 25 goals and could move up to the first team or seek new challenges. Madrid is strongly committed to giving opportunities to young talents with potential, and Naasei fits that philosophy.
The club is considering making an offer to Granada, although they know it won't be easy. The player renewed his contract until 2028 and has a release clause close to €10 million. Granada doesn't want to repeat the mistake with Samu Omoridion, who was sold to Atlético for a figure they now consider low.
An unexpected change for the club's defense?
Real Madrid could be preparing an unexpected change. Replacing an established player like Rüdiger with a young prospect from Granada sounds risky. But modern soccer requires planning and betting on the future; if Naasei manages to adapt and grow at Castilla, he could be a long-term solution for the club's defense.
Meanwhile, Madrid will keep a close eye on the German's progress and won't miss opportunities in the market. This season promises interesting moves in the back line of the world's most successful club.
