Manchester United plan 2027 defensive reset as Martinez and Dalot face uncertain futures

Manchester United are preparing a major restructuring of their back line in 2027, with a series of exits expected to accompany new defensive arrivals and two senior defenders potentially moving on as part of a broader squad reset.

The club has already focused heavily on the front half of the pitch in recent years, overhauling the attack in 2025 and reshaping midfield options in 2026. Attention is now turning towards a defensive rebuild, with recruitment in that area expected to be a central theme of United’s long-term planning.

While reinforcements at the back could arrive as early as the upcoming winter transfer window, the club’s priority in January is still the striker position. The defensive revamp is therefore more likely to be phased in across multiple windows rather than completed in a single burst of activity.

One in, one out as wage bill constraints shape transfer strategy

United’s hierarchy are understood to be working under clear financial and squad-management parameters: for every new senior player that arrives, one will leave. That approach is designed to keep the wage bill under control rather than allow it to expand with each transfer window.

The club’s leadership have been assessing the current squad with an emphasis on players who could command a worthwhile fee, especially those who have struggled to establish themselves or are no longer viewed as central to the long-term project at Old Trafford.

There is an internal recognition that the club cannot simply continue to add salaries and invest heavily in signings without making meaningful progress on outgoings. That calculation is particularly relevant under the cost-control and squad-registration framework in domestic and European competitions overseen by bodies such as the Premier League.

Martinez future in focus as contract runs down

One of the key figures at the heart of this shift is Lisandro Martinez. The defender has been singled out in recent reporting as a player whose performances have come under scrutiny, with suggestions that he has been directly involved in goals conceded on a regular basis this season.

Martinez is now in the final year of his current contract. Crucially, the Argentine does not want United to exercise their option to extend that deal by a further year, a stance that places additional pressure on the club to decide whether to pursue a renewal on different terms, cash in before he can leave for free, or allow the agreement to run down.

Unverified reports have also suggested that Martinez already has an agreement in principle with Atletico Madrid. Those claims have not been formally confirmed, but a more recent update has indicated that Martinez does want to move to the Spanish club and that a switch to Atleti is his preferred next step.

Should he depart, United would be losing a defender who has been a prominent part of their recent plans but who is now linked closely with a move to La Liga and a different tactical environment. For the player, a transfer at this stage of his career would represent a significant crossroads, potentially reshaping his role at the top level of European football.

Dalot’s position under review amid contract scrutiny

Alongside Martinez, right-back Diogo Dalot has emerged as another potential departure as United’s defensive reshuffle gathers pace. Interest from clubs across Europe has been reported, with those sides monitoring his contract situation closely.

Dalot, 27, has recently gone beyond 250 appearances for United, underlining his status as an experienced and durable member of the squad. His current contract at Old Trafford runs to 2028, so there is no immediate risk of him leaving for nothing, but that duration also makes him a player who could generate a substantial fee if the club opt to sell during the next phase of squad turnover.

The defender has been criticised for sub-par performances this season, and sections of the fanbase regularly highlight his limitations, portraying him as ineffective in attack and vulnerable defensively. Those perceptions, fair or otherwise, feed directly into the debate over whether United should continue to build around him or look to refresh the position as part of the wider defensive overhaul.

Defensive rebuild and the wider competitive picture

United’s intention to strengthen at the back in the coming windows follows a period in which resources were primarily directed towards attacking and midfield reinforcements. The club now appears to be rebalancing the squad to ensure the defensive unit aligns with ambitions in domestic and European competition.

At elite level, defensive stability underpins challenges for league titles, top-four finishes and deep runs in continental tournaments. If key defenders leave without being adequately replaced, United risk undermining progress made further up the pitch. Conversely, a successful reset at the back could support a more consistent points return across a long Premier League season and improve the team’s resilience in knockout ties.

From a strategic standpoint, United’s approach also reflects the modern reality of roster building in top-flight European football:

• Senior players entering the final stages of their contracts, such as Martinez, can quickly shift from core assets to potential exit candidates if renewals are not aligned with club plans.
• Long-serving figures like Dalot, even with contracts running to 2028, may be moved on if their roles diminish or if their market value is judged to be at its peak.
• A strict “one in, one out” policy on senior wages is intended to ensure that any major new signings in defence are financially sustainable and do not jeopardise compliance with spending controls.

Implications for United’s squad-building timeline

In practical terms, the club’s stance means that the next few windows are likely to be characterised by targeted, rather than scattergun, activity. With the striker position expected to take precedence in January, any early defensive deals would require outgoings to be lined up in parallel.

Looking ahead to 2027, the expectation is that United will seek to reshape their back line around defenders who better fit the long-term tactical and financial plan. If Martinez does secure a move to Atletico Madrid and Dalot’s situation evolves towards a transfer, those exits would create both gaps and opportunities.

For the players involved, potential moves would offer fresh environments and different competitive challenges. For United, the decisions taken now on contracts and sales will help define whether the next iteration of the squad is capable of sustaining a credible push for major honours or remains caught between short-term fixes and long-term planning.

What is clear at this stage is that United’s leadership see the coming cycle not simply as another transfer window, but as a structural recalibration. The defensive department, long identified by supporters and analysts alike as an area requiring attention, is now firmly in the spotlight as the club enters the next phase of its rebuild.
