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 defeat quickly became a hallmark of former manager Rubén Amorim's tenure, symbolising a night of profound disappointment for the club. While the recent loss to Brighton at Old Trafford may not carry the same historic weight, it shares unsettling parallels for Michael Carrick, the man who succeeded Amorim.

Youri Tielemans, United's captain during the Brighton match, confessed after the game that once the visitors went two goals ahead, his side simply stopped trying. The decline was obvious on the pitch: after about twenty minutes, Brighton began to dominate, and the contest seemed destined to end in their favour. Even the introduction of high‑profile names such as Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha failed to spark any meaningful revival. For Carrick, this lack of response is deeply concerning.

Since taking charge in January, Carrick has endured a handful of defeats, yet he has consistently highlighted positives and defended his players. Against Brighton, however, there was little to salvage. The inability to turn the tide, despite multiple substitutions, underscores a growing unease surrounding his leadership. When Carrick and his coaching team first arrived, they were lauded for tightening the defence, which produced impressive victories over rivals Manchester City and Arsenal.

The arrival of experienced figures like Steve Holland, Jonathan Woodgate and Jonny Evans contributed to a more compact back line. Nonetheless, the current season has exposed lingering frailties: United have conceded two goals in three of their four Premier League fixtures. The Brighton defeat laid those defensive issues bare.

One of the goals resulted from a mistake by goalkeeper Karl Darlow, but beyond the individual errors, the back four displayed a lack of cohesion and clear understanding of their roles. This disorganization raises questions about the defensive structure that once seemed so promising.

A persistent problem for Carrick is the left‑back position. Although he has not publicly singled out this area as a weakness, the issue is evident. Luke Shaw, United's most experienced left‑back, has missed the last three games due to a minor injury. Given Shaw’s age and his injury history—despite a strong availability record last season—it was arguably short‑sighted not to reinforce that spot during the summer transfer window.

Carrick experimented with Noussair Mazraoui in the role, yet Mazraoui appears to have slipped down the pecking order, with the less seasoned Patrick Dorgu being chosen for the Manchester derby loss. Meanwhile, the young prospect Harry Amass does not seem to be viewed as a long‑term solution. The club must therefore decide how to address this deficiency for the remainder of the campaign. Criticising Carrick’s job security after only a few weeks of the new season seems premature.

Since his return, United have amassed the highest point total of any team that has played a comparable number of games. However, Carrick himself acknowledged that moments such as Ainsley Maitland‑Niles’ equaliser for Everton, a contentious VAR decision against City, and the recent collapse versus Brighton have altered the atmosphere around the club.

A defeat to Fulham on Sunday, broadcast live on Sky Sports, could ignite uncomfortable debates about whether Carrick can navigate United out of the current storm. While those conversations may belong to a later date, it is clear that the head coach deserves some empathy given the squad he inherited. The summer transfer window saw limited outgoing activity, which hampered United’s ability to bring in fresh talent. Yet this limitation does not absolve the club of responsibility for neglecting key areas.

The left‑back slot, as previously noted, should have been reinforced. Additionally, with striker Benjamin Šeško nursing a shin injury throughout the summer, United might have considered signing a temporary No.9 to share the burden, rather than deploying Mbeumo and Cunha in unfamiliar positions.

Both forwards have struggled to recapture the form they displayed under Carrick 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 boos that echoed around Old Trafford after the Brighton loss—an expression not only of frustration with the performance but also of a broader sense of déjà vu, a feeling that the club is once again stuck in a familiar loop of fleeting optimism followed by disappointment.

It is still early days, and Carrick deserves the benefit of time after delivering a respectable campaign last season. Nevertheless, the challenges he faces are real, and ultimately he will be the one judged on how effectively he steers the ship through these choppy waters. If he can halt the downward spiral—perhaps even without a win against Fulham, provided the performance shows promise—there may be sufficient breathing room for him to realign United’s trajectory and guide the team back onto a steadier course.
