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 unexpected defeat has become almost synonymous with the brief tenure of former manager Rubén Amorim, marking a low point that still haunts the club. While Wednesday's home loss to Brighton may not have carried the same historic weight, it echoed familiar patterns for Michael Carrick, the man who succeeded Amorim at the helm.

Youri Tielemans, United's captain during the Brighton game, confessed after the final whistle that once the team fell behind 2-0, their spirit seemed to evaporate. The lack of urgency was evident throughout the match, and from roughly the 20-minute mark onward, it was clear that Brighton were dictating the tempo and that the contest was slipping away from United's grasp. Even with the introduction of attacking talents such as Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha, the Red Devils failed to generate any meaningful threat.

This inability to respond will undoubtedly be a source of deep concern for head coach Michael Carrick. Since his return to Old Trafford in January, Carrick has often praised his squad after setbacks, highlighting positive moments or individual improvements. However, against Brighton there was little to celebrate, and the performance offered no redemption. When Carrick and his coaching team first arrived, they were greeted with a wave of optimism.

Defensively, the side appeared organized and compact, which helped produce impressive victories over rivals Manchester City and Arsenal. The arrival of experienced figures such as Steve Holland, Jonathan Woodgate and Jonny Evans seemed to tighten the back line instantly.

Yet the current season has exposed lingering frailties in that same defence. United have now allowed two goals in three of their four Premier League fixtures, a statistic that raises questions about the solidity that many believed had been restored. The Brighton defeat highlighted these issues once more.

While one of the goals was the result of a clear error from goalkeeper Karl Darlow, the broader problem lay in the lack of cohesion and understanding among the back four, which appeared disjointed and uncertain. A persistent problem for Carrick has been the left‑back position.

Although he has not publicly labeled it a weakness, the deficiency is evident, and the club’s hierarchy was aware of it heading into the summer transfer window. Senior left‑back Luke Shaw, the only seasoned option, missed the last three games due to a minor injury. Given Shaw’s age and his history of recurring niggles—despite his impressive availability last season—it was arguably short‑sighted not to reinforce that area.

Carrick has experimented with Noussair Mazraoui in the role, but the Moroccan appears to have slipped down the pecking order, with the less experienced Patrick Dorgu being preferred for the Manchester derby loss. Young prospect Harry Amass has also not been earmarked as a long‑term solution. Consequently, United face a pressing dilemma: how to plug the left‑back gap for the remainder of the campaign? It may seem premature to question Carrick’s job security after only a handful of league matches in the new season, especially since the team still holds the highest points total accumulated under his leadership since his January appointment.

Nevertheless, Carrick himself has acknowledged that moments such as Ainsley Maitland‑Niles’ equaliser for Everton, a controversial VAR decision against Manchester City, and the recent collapse versus Brighton have altered the narrative around his tenure. If United were to suffer another defeat—say, a loss to Fulham on Sunday, broadcast live on Sky Sports—there would inevitably be uncomfortable debates about whether Carrick can guide the club out of the current storm. While those discussions may be premature, the head coach does deserve some empathy given the constraints he has inherited. The summer transfer window saw very limited outgoing activity, leaving United with a squad that lacked depth in key areas.

This scarcity of sales and purchases hampered the club’s ability to reinforce adequately. Yet, does that excuse the failure to address obvious weaknesses?

The left‑back spot, as mentioned, should have been a priority. Moreover, with striker Benjamin Šeško nursing a shin injury throughout the summer, United might have benefited from bringing in a temporary No 9 to share the load, rather than deploying Mbeumo and Cunha in unfamiliar positions. 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 are likely to remain trapped in a cycle of incremental signings—mostly players left over from previous regimes—without achieving the structural change required for sustained success.

This reality may explain the audible discontent from the Old Trafford stands after the Brighton loss; the boos were not solely directed at the performance but also at the sense of déjà vu, a feeling that the club is once again stuck in a repeating pattern of early promise followed by disappointment. Although it is still early days, and Carrick merits patience after the progress he delivered last season, the challenges he now faces are significant. He must navigate these troubled waters, balancing tactical adjustments with squad reinforcement, while under the constant scrutiny of a demanding fan base.

If he can halt the downward spiral—perhaps even without a win against Fulham, but by delivering a convincing performance—there may be enough time for him to steer Manchester United back onto a steadier course. The journey ahead will be demanding, but the potential for redemption remains within reach if the manager can marshal his resources effectively and inspire belief across the stadium.
