Marc Cucurella’s request to leave Chelsea this summer has sent shockwaves through the Stamford Bridge hierarchy. The 23-year-old Spanish international, who has been a mainstay at left-back for the past three seasons, reportedly wants out after the club’s disappointing Champions League campaign. While Cucurella remains at the club for now, his future is far from certain as Chelsea look to strengthen their squad ahead of what promises to be a highly competitive 2026-27 season.

The departure of Cucurella would leave a significant hole in Chelsea’s defense, particularly given the club’s recent struggles in the Premier League. With only two left-backs currently under contract beyond the 2025-26 season—Reece James and Ben Chilwell—manager Thomas Tuchel faces a critical decision about how to address this positional weakness.

As the summer transfer window approaches, Chelsea’s technical staff have been scouting potential replacements with intensity. While no formal target list has been confirmed, three names have consistently emerged in discussions among industry insiders and former club officials. These players represent different profiles—youth, experience, and technical ability—that could appeal to Tuchel’s tactical requirements.

1. João Neves: The High-Octane Portuguese Prospect

Benfica’s João Neves, 19, has been the most frequently mentioned name in connection with Chelsea. The Portuguese international has drawn comparisons to former Chelsea star César Azpilicueta, both for his attacking prowess and his ability to progress play from the left flank.

Neves has been in demand across Europe this summer, with clubs from the Premier League to La Liga interested in his services. His performances for Benfica in the Champions League, where he scored a crucial goal against Bayern Munich, have only heightened his profile. However, Chelsea would need to navigate competition from other top clubs, including Manchester City and Real Madrid, who are also keen to sign the youngster.

While Neves would bring energy and creativity to Chelsea’s left-back position, his lack of Premier League experience could be a concern. Tuchel would need to carefully assess whether the young Portuguese is ready for the physical demands of England’s top flight.

2. Achraf Hakimi: The Seasoned Leader with Champions League Pedigree

Paris Saint-Germain’s Achraf Hakimi remains one of the most coveted left-backs in world football. The 24-year-old Moroccan international has been linked with Chelsea in the past, and with his contract at PSG expiring in 2027, the timing could be right for a move to London.

Hakimi’s experience in the Champions League, where he has been a key player for both PSG and previously Real Madrid, would be invaluable for Chelsea as they look to reclaim their place among Europe’s elite. His ability to defend in one-on-one situations and his composure in high-pressure moments make him an ideal candidate for Tuchel’s system.

However, Hakimi’s agent has reportedly set a high price tag, and Chelsea would need to be prepared to meet or exceed PSG’s valuation of the player. Hakimi’s personal preference for a return to La Liga or Serie A could complicate negotiations.

3. Ryan Gravenberch: The Dutch Dynamite from Ajax

Ajax’s Ryan Gravenberch has emerged as a dark horse candidate for Chelsea’s left-back position. The 21-year-old Dutch international is a versatile player who can operate as a left-back, central midfielder, or even in a false winger role, making him an intriguing tactical option for Tuchel.

Gravenberch’s technical ability and creativity from the left flank have drawn comparisons to former Chelsea player Bernardo Silva. His performances in the Eredivisie and Europa League have caught the attention of several top clubs, including Chelsea, who are always on the lookout for young, talented players with Premier League potential.

One potential drawback is Gravenberch’s lack of defensive experience in a dedicated left-back role. While he has played there for Ajax, his primary position is in midfield, which could require a period of adaptation if he were to join Chelsea. Nonetheless, his attacking qualities and Premier League-ready talent make him an appealing option for a club looking to build for the future.

Tactical Considerations: How Tuchel Might Deploy a New Left-Back

Thomas Tuchel’s tactical flexibility is one of his greatest strengths, and the arrival of a new left-back could open up new possibilities for Chelsea’s system. Depending on the profile of the incoming player, Tuchel could explore several formations and roles:

• Traditional Left-Back: A player like Hakimi or Cucurella would slot neatly into a three-at-the-back system, providing width and defensive solidity.
• Inverted Left-Back: Neves or Gravenberch could be used in a more advanced role, cutting inside to link play and create overloads on the left flank.
• False Winger: Gravenberch’s versatility could allow Tuchel to experiment with a more attacking left-back, similar to how Chelsea used Reece James in certain phases of play last season.

The choice of formation would also depend on Chelsea’s other defensive options. With Ben Chilwell and Reece James already in the squad, Tuchel has flexibility to adjust his backline based on the strengths of his new signing. For example, if Chelsea bring in a more defensively solid left-back like Hakimi, Tuchel might opt for a more traditional three-at-the-back setup. Conversely, if they target a more attacking option like Neves or Gravenberch, he could experiment with a back three that prioritizes width and creativity.

Financial Realities: Can Chelsea Afford Their Dream Left-Back?

Chelsea’s financial situation remains a critical factor in their transfer strategy. While the club has made progress in recent years under owner Todd Boehly, they still operate with constraints compared to their Premier League rivals Manchester City and Arsenal.

According to Transfermarkt, the three players discussed here have the following estimated transfer values:

Chelsea would likely need to structure any transfer around a combination of cash and add-ons, potentially involving the sale of existing squad members. Players like Mason Mount, Enzo Fernández, or even a potential loan deal for a youngster could be part of the equation to free up funds for a high-profile signing.

Chelsea may explore the possibility of signing a player on a long-term contract with a lower initial transfer fee but with significant future add-ons. This approach has been used successfully in the past, such as in the cases of Enzo Fernández and Moisés Caicedo.

What Happens If Chelsea Fail to Sign a Left-Back?

The potential departure of Marc Cucurella combined with the lack of a clear replacement plan could leave Chelsea in a precarious position. Here are the possible scenarios:

• Emergency Loan Signing: Chelsea could look to the loan market in January to address the short-term need, similar to how they signed Moisés Caicedo from Las Palmas last season.
• Development of Youth Players: The club could accelerate the development of young left-backs like Conor Gallagher or Jack Gallagher, who have shown promise in recent seasons.
• Tactical Adjustments: Tuchel might need to adapt his system to minimize the impact of the left-back shortage, potentially by reducing the team’s attacking width or using Mason Mount in a more defensive role at times.
• Extended Loan for Cucurella: If Cucurella’s request to leave is granted, Chelsea could explore the possibility of loaning him out for the season to regain some of their investment, similar to how they loaned out Pedro Porro to Roma last season.

The most immediate concern is how this positional weakness could affect Chelsea’s Champions League qualification campaign. With only two left-backs currently under contract beyond next season, the club would need to ensure that at least one of them remains fit and available for the majority of the campaign. Injuries to either Reece James or Ben Chilwell could create significant problems down the line.
