Manchester United suffered a memorable defeat in the Carabao Cup second round against Grimsby Town last season, a loss that has become almost synonymous with the brief tenure of former manager Rubén Amorim. While that particular setback was a stark reminder of the club's vulnerabilities, the more recent home defeat to Brighton & Hove Albion, though less dramatic, echoed many of the same issues for Michael Carrick, who succeeded Amorim at the helm.
Youri Tielemans, United's captain on the day of the Brighton loss, was candid in post‑match interviews, admitting that once the team fell behind 2-0 they essentially stopped playing with any conviction. The atmosphere at Old Trafford from roughly the 20‑minute mark onward made it clear that Brighton were dictating the tempo, and despite United's attempts to inject fresh energy by bringing on Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha, the visitors remained largely unthreatened. This lack of impact is precisely the type of scenario that should concern Carrick.
Since taking over in January, Carrick has endured a handful of defeats, yet he has consistently highlighted the positives and defended his squad's effort. Against Brighton, however, there was little to salvage. The match offered no redeeming moments, no tactical adjustment that turned the tide, and no individual brilliance that could offset the collective underperformance. When Carrick and his coaching team first arrived, they were lauded for tightening a previously leaky defence and for engineering impressive victories over rivals Manchester City and Arsenal.
The arrival of experienced figures such as Steve Holland, Jonathan Woodgate and Jonny Evans seemed to instantly raise the defensive standards. Yet the current season has exposed lingering frailties; United have allowed two goals in three of their four Premier League fixtures, a statistic that points to systemic issues rather than isolated errors.
The Brighton game highlighted these defensive shortcomings once again. While one of the goals was attributable to a clear mistake by goalkeeper Karl Darlow, the broader problem lay in the lack of cohesion among the back four. The unit appeared disjointed, with poor positioning and inadequate communication, suggesting that the defensive shape has not yet fully internalised Carrick's tactical blueprint. A particular area of concern remains the left‑back position.
Carrick has not publicly labelled it a weakness, but the evidence suggests otherwise. Luke Shaw, United's senior left‑back, has been sidelined for his third consecutive match due to a minor injury. Given Shaw's age, his injury history and the fact that he was a reliable option last season, many observers argue that the club should have bolstered this position during the summer transfer window.
Carrick has experimented with Noussair Mazraoui in the role, yet Mazraoui seems to have slipped down the pecking order, with the less experienced Patrick Dorgu being preferred for the Manchester derby that preceded the Brighton defeat. Meanwhile, the young prospect Harry Amass does not appear to be in the club's long‑term plans for that spot. The lingering question, therefore, is how United will address this deficiency for the remainder of the campaign. Critics who question Carrick's job security after only a few weeks of the new season may be premature.
Since his return, United have amassed the highest point total of any side that has played under his guidance. Nevertheless, Carrick himself has acknowledged that moments such as Ainsley Maitland‑Niles' equaliser for Everton, a contentious VAR decision against Manchester City, and the recent collapse versus Brighton have altered the narrative surrounding his tenure. Looking ahead, a loss to Fulham on Sunday—broadcast live on Sky Sports—could ignite a more serious debate about whether Carrick can navigate United out of the current storm. While it might be too early to pronounce verdicts, the head coach deserves some sympathy given the constraints he has faced.
One of those constraints has been the limited activity in the summer transfer market. The lack of significant outbound transfers left the squad relatively unchanged, meaning United were unable to address key gaps effectively. The left‑back position, as previously mentioned, should have been a priority. Moreover, with Benjamin Šeško still nursing a shin injury throughout the summer, United might have benefited from securing a temporary No.9 to share the burden, rather than forcing Matheus Cunha and Bryan Mbeumo into roles that do not suit their natural strengths.
Both forwards have struggled to recapture the form they displayed under Carrick's guidance last season. Until United can execute a comprehensive squad overhaul in a single transfer window, they will likely remain trapped in a cycle of incremental reinforcements, relying heavily on players inherited from previous regimes. This perpetual state of partial improvement may be why some supporters expressed their displeasure with boos after the Brighton defeat—not solely directed at the performance itself, but also reflecting a broader frustration with a perceived pattern of false dawns following promising starts under new managers.
It is still early days, and Carrick deserves the benefit of time, especially considering the achievements of the previous season. However, the waters he must navigate are undeniably choppy. The ultimate judgment will rest on his ability to halt the downward spiral, even if the next match does not produce a victory but simply a more convincing display. If he can steady the ship and steer United back onto a stable course, patience may yet be rewarded.
