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 tenure of former head coach Ruben Amorim, marking a low point that still lingers in the club’s recent history. While the recent 2-0 defeat to Brighton at Old Trafford may not have carried the same historic weight, it echoed similar themes for Michael Carrick, the manager who succeeded Amorim. Youri Tielemans, United’s captain during the Brighton match, admitted after the game that once the team fell behind by two goals, their energy and intent evaporated.

The shift was evident within the first twenty minutes, as Brighton began to dominate possession and create chances, leaving United appearing passive and disjointed. Despite the introduction of attacking options such as Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha, the Red Devils failed to generate any meaningful threat, a scenario that will undoubtedly trouble Carrick. Since returning to the club in January, Carrick has weathered a handful of defeats but has often highlighted positive aspects of his squad’s performances. The Brighton loss, however, offered little in the way of redemption.

It was a stark reminder that the early optimism surrounding his appointment is being tested. When Carrick and his coaching team first took charge, they earned considerable praise for tightening the defensive structure.

The side produced impressive victories over rivals Manchester City and Arsenal, with the defensive unit benefitting from the experience of Steve Holland, Jonathan Woodgate and Jonny Evans. Yet, the same defense now appears porous; United have conceded two goals in three of their last four Premier League fixtures. The Brighton game exposed these defensive frailties once more. While one of the goals resulted from a clear mistake by goalkeeper Karl Darlow, the broader issue lay in the lack of cohesion and organization among the back four.

The shape was inconsistent, and the players seemed uncertain about their responsibilities, leading to an unsettling lack of coherence. Left‑back remains a particular Achilles’ heel for Carrick.

Although he has not publicly singled out the position as a weakness, the problem is evident. Luke Shaw, United’s senior left‑back, has missed the previous three matches due to a minor injury.

Given Shaw’s age and his injury history, it was perhaps shortsighted not to reinforce that area during the summer transfer window. Carrick has trialed Noussair Mazraoui in the role, but the Moroccan appears to have slipped down the pecking order, with the less experienced Patrick Dorgu preferred for the Manchester derby loss. Meanwhile, young prospect Harry Amass does not seem to be in the long‑term plans for the position, leaving a clear question about 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 accumulated the highest point total of any team since his January appointment. However, Carrick himself has acknowledged that moments such as Ainsley Maitland‑Niles’ equaliser for Everton, the controversial VAR decision against Manchester City, and now the disappointing performance versus Brighton have altered the atmosphere around the club. A loss at Fulham on Sunday, broadcast live on Sky Sports, could trigger uncomfortable debates about whether Carrick can navigate United out of the current storm.

While that conversation may belong to a later date, it is fair to extend some sympathy to the manager, given the constraints he faces. The summer transfer window saw limited outgoing activity, which has hampered United’s ability to strengthen the squad adequately. Yet, this does not fully excuse the failure to address obvious needs, particularly at left‑back. Moreover, the decision to rely on players like Mbeumo and Cunha in unfamiliar roles, rather than securing a temporary striker to share the burden while Benjamin Šeško recovered from a shin injury, has backfired.

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 are likely to remain stuck in a cycle of incremental improvements using remnants from previous regimes. This reality may explain the boos that echoed around Old Trafford after the Brighton defeat—not solely a reaction to the performance, but a manifestation of frustration with a perceived repeating pattern of false dawns under new managers.

Although it is still early days, and Carrick deserves patience for the progress he achieved last season, the waters he must navigate are undeniably turbulent. His future will be judged on his ability to halt the decline and, ideally, to steer the club back onto a stable trajectory. Even if a win against Fulham does not materialise, a solid performance could buy him valuable time to correct course and restore confidence among the supporters.

In summary, Michael Carrick faces a critical test: to address defensive inconsistencies, resolve the left‑back crisis, and make strategic signings that strengthen the squad without compromising its balance. How he manages these challenges will determine whether Manchester United can regain its footing or continue to drift in a sea of uncertainty.
