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 has become almost emblematic of the period when former manager Rubén Amorim was at the helm, a chapter that is often recalled when discussing the club's recent struggles. While the recent 2-0 defeat to Brighton at Old Trafford did not carry the same historical weight, it nonetheless echoed many of the same themes that plagued the team under Amorim, and now it falls squarely on the shoulders of his successor, Michael Carrick.

Youri Tielemans, who captained United on the day of the Brighton loss, was candid in the post‑match interview. He admitted that once United fell two goals behind, the side simply stopped competing with any urgency, a sentiment that was painfully evident throughout the 90 minutes.

From roughly the 20‑minute mark onward, Brighton seized control of the game, dictating the tempo and forcing United onto the back foot. 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, and the match slipped further away. For Carrick, this lack of resilience is deeply concerning. Since taking over in January, he has often praised his players and highlighted the positives in each performance, even after a string of defeats.

However, against Brighton there was no silver lining to be found. The inability to respond when trailing, coupled with a lack of creativity in the final third, underscores a broader issue that could jeopardise his tenure if not addressed promptly. When Carrick and his coaching team first arrived, they were met with considerable optimism.

The defensive unit, bolstered by the experience of Steve Holland, Jonathan Woodgate and the ever‑reliable Jonny Evans, appeared tighter and more disciplined. This newfound solidity helped United secure impressive victories over rivals Manchester City and Arsenal, suggesting that the new regime could restore the club’s competitive edge.

Nevertheless, the defensive frailties that have resurfaced this season cannot be ignored. United have conceded two goals in three of their four Premier League fixtures, a statistic that points to systemic issues rather than isolated mistakes. The Brighton match highlighted these vulnerabilities starkly.

While one of the goals resulted from a clear error by goalkeeper Karl Darlow, the overall shape of the back line was disjointed, with the four defenders failing to maintain a cohesive structure or communicate effectively. One area that has drawn particular scrutiny is the left‑back position. Carrick has not publicly identified this as a weakness, yet the data and on‑field performances tell a different story. Luke Shaw, United’s senior left‑back, has missed the last three games due to a minor injury.

Given Shaw’s age, his injury history, and the fact that he was remarkably available throughout the previous season, it was perhaps short‑sighted not to reinforce that spot during the summer transfer window. Carrick experimented with Noussair Mazraoui in the role, but Mazraoui quickly fell down the pecking order, with the less experienced Patrick Dorgu being preferred for the high‑profile Manchester derby loss. Meanwhile, the academy prospect Harry Amass does not appear to be a long‑term solution.

The club now faces a dilemma: how to plug the left‑back gap for the remainder of the campaign without a clear sign‑on target. Critics might argue that it is premature to question Carrick’s job security after only a handful of games in the new season. On paper, United have amassed the highest points total since his return in January, a statistic that should provide some cushion.

Yet, as Carrick himself acknowledged, moments such as Ainsley Maitland‑Niles’ equaliser for Everton, the controversial VAR decision that awarded Manchester City a goal, and the recent collapse against Brighton have dramatically altered the narrative surrounding his tenure. The upcoming fixture against Fulham, broadcast live on Sky Sports, could prove pivotal. A loss would likely intensify the debate about whether Carrick can navigate United out of the current storm. While it may be too early to make definitive judgments, the manager does deserve some empathy given the constraints he has faced.

One of the most significant challenges has been the lack of player turnover this summer. United’s transfer activity was relatively muted, limiting their ability to address key deficiencies. The left‑back issue, as previously mentioned, should have been a priority. Additionally, the forward line has struggled to adapt.

Benjamin Šeško spent much of the pre‑season nursing a shin injury, and the club opted not to secure a temporary No 9 to share the goal‑scoring burden. Instead, they have relied on Matheus Cunha and Bryan Mbeumo, both of whom have been deployed out of their natural positions and have yet to recapture the form they displayed under Carrick’s previous spell. Ultimately, United appear trapped in a cycle of incremental reinforcement, relying heavily on players inherited from previous regimes.

This approach has resulted in a sense of déjà vu among the fanbase, as evidenced by the boos that rang out at Old Trafford after the Brighton defeat. Those chants were not solely directed at the performance on the day but reflected a broader frustration with a perceived pattern of false dawns following promising starts under new managers.

It is still early in the season, and Carrick deserves the time to build on the foundations he laid last year. However, he must now navigate a precarious set of waters, balancing short‑term results with long‑term squad development.

If he can halt the downward spiral—perhaps even without an immediate win against Fulham but by delivering a convincing performance—there is a chance that patience will be rewarded and the ship can be steered back onto a steady course. In summary, Michael Carrick faces a critical test. The combination of defensive inconsistencies, a vulnerable left‑back position, and an under‑performing attack creates a perfect storm that threatens United’s ambitions. Yet, with strategic adjustments, astute use of the transfer market, and a renewed focus on tactical cohesion, there remains a realistic pathway for Carrick to restore confidence and guide Manchester United back to the heights expected of them.
