Manchester United’s early exit from the Carabao Cup at the hands of Grimsby Town last season remains a vivid memory for many supporters. That loss became almost emblematic of the period when former manager Rubén Amorim was in charge, marking a low point that still haunts the club. While the recent defeat at Old Trafford against Brighton may not carry the same historic weight, it echoes similar patterns for Michael Carrick, the man who succeeded Amorim. Youri Tielemans, United’s captain during the Brighton game, admitted after the match that once United fell two goals behind, the team essentially stopped competing.

The shift in momentum was evident within the first twenty minutes, as Brighton began to dominate and the contest seemed destined to end in their favour. Even after the introduction of attacking options such as Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha, United failed to generate any meaningful threat. This lack of response is precisely the type of scenario that will keep Carrick awake at night. Since returning to the club in January, Carrick has endured a handful of setbacks but has consistently tried to highlight the positives in his side’s displays.

Against Brighton, however, there was little to salvage. The manager’s usual habit of finding a silver lining was absent, and the performance offered no redemption. When Carrick and his coaching staff first arrived, they were greeted with considerable optimism.

The team’s defensive shape appeared tighter and more disciplined, leading to impressive victories over rivals Manchester City and Arsenal. The arrival of experienced figures such as Steve Holland, Jonathan Woodgate and Jonny Evans contributed instantly to a more robust back line. Nevertheless, questions now arise regarding the defensive frailties that have resurfaced this season.

United have conceded two goals in three of their four Premier League matches, a statistic that signals a worrying trend. The Brighton loss laid those vulnerabilities bare once again.

While one of the goals resulted from a mistake by goalkeeper Karl Darlow, the broader issue was the lack of cohesion and understanding among the back four, which seemed disjointed and poorly organized. A persistent problem for Carrick is the left‑back position. Although he has not publicly singled out the area as a specific weakness, the deficiency is evident.

The club entered the summer transfer window aware of this shortfall, yet the solution has remained elusive. Luke Shaw, United’s senior left‑back, missed his last three outings due to a minor injury.

Given his age and a history of recurring niggles—despite an impressive availability record last season—it was arguably naive not to pursue a more reliable alternative. Carrick experimented with Noussair Mazraoui in that role, but the Moroccan appears to have slipped down the pecking order, with the less experienced Patrick Dorgu preferred for the high‑stakes Manchester derby that also ended in defeat. Meanwhile, youngster Harry Amass does not seem to be viewed as a long‑term answer.

The pressing question, then, is how United will address the left‑back vacancy for the remainder of the campaign. It may seem premature to discuss Carrick’s job security after only a few weeks of the new season, especially since United have amassed the highest point total of any side since his January appointment.

Yet, as the manager himself acknowledged, moments such as Ainsley Maitland‑Niles’ equaliser for Everton, the controversial VAR decision against City, and now the collapse at Brighton have altered the narrative dramatically. A defeat to Fulham on Sunday, broadcast live on Sky Sports, could ignite uncomfortable debates about whether Carrick is capable of guiding United out of the current storm. While that discussion may belong to a later date, it is worth noting that Carrick deserves some empathy for the squad he has inherited.

The lack of significant player sales and limited incoming transfers this summer has constrained United’s ability to reinforce key areas. Nevertheless, this limitation does not absolve the club of responsibility for neglecting crucial positions. The left‑back slot, as highlighted, should have been bolstered. Moreover, with Benjamin Šeško still nursing a shin injury throughout the summer, United might have benefited from signing a temporary No.9 to share the load, rather than deploying Mbeumo and Cunha out of position.

Both forwards have struggled to recapture the form they displayed under Carrick’s guidance last season. Until United can execute a comprehensive overhaul in a single transfer window, they will likely remain trapped in a cycle of incremental upgrades using remnants from previous regimes. This pattern may explain the audible boos that echoed around Old Trafford after the Brighton loss—not solely a reaction to that single performance, but a broader expression of frustration with a recurring cycle, a sense of déjà vu from past seasons, and the disappointment of another false dawn following an initially promising start under a new head coach. Although it is still early days, Carrick deserves patience for the achievements he delivered last term.

Yet, navigating these turbulent waters will be his responsibility, and ultimately, he will be judged on the outcomes. If he can halt the downward spiral—perhaps even without securing a win against Fulham, provided the performance shows promise—time may grant him the opportunity to steer Manchester United back onto a steady course.
