Manchester United’s early‑season exit from the Carabao Cup at the hands of Grimsby Town last campaign remains a vivid memory for many supporters. That defeat became a defining moment of the brief tenure of former manager Rubén Amorim, symbolising a night that many would rather forget. While the recent 2-0 loss to Brighton & Hove Albion at Old Trafford may not carry the same historical weight, it echoes similar themes for the man who succeeded Amorim – Michael Carrick. Youri Tielemans, United’s captain on the day of the Brighton defeat, was candid in the post‑match interview.

He admitted that once United fell two goals behind, the team essentially stopped playing with purpose, a sentiment that was evident in the way the match unfolded. From roughly the 20‑minute mark, Brighton began to dominate, and despite United’s attempts to change the dynamic by introducing Bruno Fernandes, Kobbie Mainoo, Bryan Mbeumo and Matheus Cunha, the visitors failed to make a lasting impact on the game. This lack of response is precisely the kind of issue that will keep Carrick awake at night.

Since taking over in January, Carrick has weathered a handful of setbacks. He has consistently defended his players, highlighting positive aspects of their performances, but the Brighton game offered no redemption. The inability to turn the tide, even after a flurry of substitutions, underscored a deeper problem that goes beyond a single match.

When Carrick and his backroom staff first arrived, they were lauded for tightening a defence that had previously seemed porous. The early signs were promising: United secured impressive victories over Manchester City and Arsenal, and the arrival of experienced figures such as Steve Holland, Jonathan Woodgate and Jonny Evans appeared to fortify the back line. However, the current season has raised fresh questions about the solidity of that same defence. United have now conceded two goals in three of their four Premier League fixtures, a statistic that cannot be ignored.

The Brighton loss laid bare the defensive frailties once more. One of the goals resulted from a clear mistake by goalkeeper Karl Darlow, but beyond that, the organization of the back four seemed chaotic. The unit lacked cohesion, and the players appeared uncertain about their roles, leading to a loss of shape that Brighton exploited ruthlessly.

A persistent concern for Carrick is the left‑back position. Although he has not publicly singled out the area as a glaring weakness, the issue is evident. Luke Shaw, United’s senior left‑back, has missed the last three matches due to a minor injury.

Given Shaw’s age and his injury history – despite a strong availability record last season – it was arguably shortsighted not to reinforce that spot during the summer transfer window. Carrick has experimented with Noussair Mazraoui in the role, yet Mazraoui seems to have slipped down the pecking order, with the less experienced Patrick Dorgu being preferred for the high‑stakes Manchester derby that ended in defeat. Meanwhile, the young prospect Harry Amass does not appear to be in United’s long‑term plans for the position.

The club now faces a pressing question: how will it address the left‑back vacancy for the remainder of the campaign? It may appear premature to debate Carrick’s job security after only a few weeks of the new season, especially since United have amassed the highest points total of any team since his return in January. Nevertheless, Carrick himself has acknowledged that moments such as Ainsley Maitland‑Niles’ equaliser for Everton, the controversial VAR decision that awarded Manchester City a goal, and the unsettling collapse against Brighton have altered the narrative surrounding his tenure.

If United were to suffer another defeat – for instance, a loss to Fulham on Sunday – the conversation about whether Carrick can rescue the club from its current predicament would become inevitable. While that debate may be reserved for later, it is worth noting that Carrick deserves some empathy given the constraints he has faced.

The summer transfer window saw a dearth of outgoing players, limiting United’s ability to reinvest the funds that might have been generated through sales. This lack of activity has hampered the club’s capacity to address key areas, notably the left‑back slot. Moreover, with striker Benjamin Šeško nursing a shin injury throughout the summer, United might have benefited from securing a temporary No 9 to share the burden, rather than relying on Bryan Mbeumo and Matheus Cunha in roles that do not suit their natural strengths. Both forwards have struggled to recapture the form they displayed under Carrick’s guidance last season.

In the broader context, United appear trapped in a cycle of incremental reinforcement, relying heavily on players inherited from previous regimes. This pattern was palpable in the reaction of the Old Trafford crowd after the Brighton defeat, where boos were not only directed at the performance but also reflected a deeper frustration with the perceived repetition of past cycles – a sense of déjà vu that a promising start under a new head coach is inevitably followed by disappointment. Although it may be too early to pass final judgment, Carrick must navigate these choppy waters with a steady hand.

The club’s supporters and hierarchy will ultimately decide whether he can halt the downward spiral. Even if United do not secure a victory against Fulham, a competitive performance could buy Carrick valuable time to steady the ship and steer Manchester United back onto a more promising course.
