The 2026 European summer transfer window has come to an end, but Chelsea's midfield squad still has weaknesses. In particular, the late departure of key player Enzo has forced the club to make early plans for reinforcements in the winter transfer window.

According to reports, in order to find a replacement for Enzo, manager Alonso has already listed Atletico Madrid's 23-year-old Spanish midfield star Pablo Barrios as his top transfer target and plans to officially launch an approach in January next year.
Chelsea's midfield problems have emerged this season, with the main cause being an unsuccessful summer window adjustment. Near the end of the transfer window, starting midfielder Enzo moved to Manchester City, and some industry figures believe the Blues' transfer operation lacked professionalism and disrupted the team's original midfield plans. At the same time, the club's planned deal for Monaco midfielder Kamara eventually collapsed, leaving Chelsea's alternative reinforcement plan completely unsuccessful. The continued loss of players and failed signings have significantly reduced Chelsea's midfield depth, increasing the risks of competing on multiple fronts and making winter reinforcements necessary.

The main reasons Barrios has become Chelsea's top midfield target are said to be his outstanding talent, all-round abilities, balance in attack and defense, strong running capacity, accurate passing, and skill in midfield organization and transition play. Defensively, Barrios is reliable in interceptions and positioning, has strong physical ability, and can effectively protect the back line. Offensively, he can use accurate short and long passes to control the team's rhythm, while also possessing the ability to carry the ball forward and make runs into deeper areas.
More importantly, Chelsea manager Alonso is said to have great faith in Barrios and believes he can form a perfect partnership with Caicedo. If the two were paired together, they could strengthen Chelsea's midfield structure in both attack and defense and perfectly fill the tactical gap left by Enzo's departure.

Although Barrios is still young, he established himself as a regular Atletico Madrid midfield starter from last season and has shown rapid development. During that period, he suffered a hamstring injury and missed the final part of the season and the World Cup, but he has now fully recovered and quickly returned to his best form, with a stable and mature competitive level. As a core part of Simeone's tactical system, Barrios plays a key role in linking attack and defense in Atletico's midfield. Therefore, if Chelsea want to sign this Spanish international midfielder from Atletico, it will likely not be easy.

There is no doubt that Chelsea will face many practical obstacles in signing Barrios during the winter window. According to reports, Chelsea are prepared to make a €100 million offer, but Barrios' release clause is reportedly as high as €500 million. Therefore, if Atletico do not want to sell, Chelsea may find the situation very difficult. Overall, signing Barrios in the winter window will be a major challenge for Chelsea, but it is not impossible. The club's transfer strategy will now face a major test.
