The website "Fichajes" reported that Atletico Madrid's heavy defeat against Arsenal in the third round of the UEFA Champions League for the 2025/2026 season prompted the management to prioritize strengthening the defense during the winter transfer window.

Argentinian coach Diego Simeone has informed the club's management that the team urgently needs a high-quality central defender to ensure competitiveness both domestically and in Europe. Simeone clarified that relying on the current players in central defense does not provide the necessary solutions in major matches, making the signing of a strong player essential to ensure the stability of the defensive unit.

Atletico Madrid suffered a 4-0 defeat against Arsenal, which clearly exposed the weaknesses in the defense. After conceding eight goals in three Champions League matches, it became evident that the problem is structural and not temporary. The team also conceded ten goals in nine rounds of La Liga, reinforcing the need for urgent action to bolster the defense.

Simeone has called for the signing of a central defender with physical strength, proper positioning, and the ability to lead the defense from the back. The report indicates that the sports management is currently considering several options capable of delivering immediate performance and quickly adapting to the club's playing style.

The importance of signing a top-class defender is also highlighted by Simeone's style, which demands pressing and attacking from the back, along with the ability to treat every ball with full seriousness. This makes the winter transfer window a strategic opportunity to strengthen the central defense before the resumption of European competitions.

If Atletico Madrid responds to Simeone's demands, the team will be able to regain defensive balance and compete for titles both domestically and in Europe, while failure to act may expose the current season to the risks of delay and regression.
