Manchester United’s embarrassing loss to Brighton has put manager Michael Carrick under the microscope, but the club’s difficulties run deeper than the coach’s tactical choices. United stormed into a 2-0 lead within the first ten minutes of the Wednesday night match, only to see the advantage evaporate as Brighton turned the game around and won 3-2. The defeat not only knocked United out of the Carabao Cup at the third‑round stage for the second year in a row, it also saw the home supporters turn their backs on the team, booing the players off the pitch.

It was a historic reversal. In the previous half‑century, Old Trafford had never surrendered a match after taking a two‑goal lead. Of the 145 games in which United had built a 2-0 cushion, they had emerged victorious in 143.

Moreover, after Mason Mount’s second‑minute strike, United failed to register another shot on target until the 76th minute, highlighting a sudden loss of momentum and creativity. The result has intensified pressure on Carrick, who was given the permanent job only a few months after an interim spell that earned him praise. Last season he guided United to 12 wins, three draws and two defeats in 17 games – a 70.6% win rate.

This campaign, however, tells a different story: two wins, one draw and three losses from six league fixtures, a win percentage that has slipped to roughly 33%. The club now matches its joint‑worst start after four Premier League games, and the early cup exit has removed a realistic chance of adding silverware to the season’s agenda. The core issue appears to be a lack of urgency and intensity on the field.

United currently sit 14th in the league for total distance covered – 449.1 kilometres – but their rankings tumble when the speed of those movements is examined. They rank 18th for total sprints (379), 19th for high‑speed runs (1,364), and similarly low in sprints and high‑speed runs per kilometre. In plain terms, the team is moving the ball but not at the pace required to press opponents, recover quickly, or defend transitions effectively. Against Brighton, the problem was stark.

United made nine changes from the side that had featured in the Manchester derby, inserting several players who had spent most of the previous match on the bench. Brighton, in turn, made six alterations, including four debutants, and seemed fresher and more physically prepared. Former player Jamie Redknapp summed up the sentiment on television: “They didn’t look fit enough.

I saw too many players not running back or not looking fit enough.” One vivid illustration was Leny Yoro’s recovery after Brighton’s third goal; instead of sprinting back to challenge, he was merely jogging, allowing the opposition to consolidate their lead. Fitness and intensity are not isolated concerns for a single night; they are systemic. If United cannot match the physical output of their rivals, they will be forced to defend larger spaces and spend longer periods without possession, a scenario that erodes confidence and invites further goals. The summer transfer window added another layer to the puzzle.

United splashed roughly £85 million on two midfielders – Youri Tielemans and André Santos – and paid about £70 million for striker Carlos Baleba, who watched the Brighton game from the stands. In total, the club spent on seven permanent signings and four loan arrivals while letting 13 players leave permanently and loaning out another ten. The squad’s market value, according to Transfermarkt, now sits at £791.2 million, the fifth‑highest in the Premier League behind City, Arsenal, Chelsea and Liverpool. However, the distribution of that value raises questions.

The attacking unit accounts for £317.2 million, midfield for £249.9 million, and the defensive group – the area that has drawn the most criticism – is valued at only £193.8 million, with the goalkeeper portion making up the balance. The defensive line entered the Brighton match with two inexperienced centre‑backs, Leny Yoro and Ayden Heaven, and limited depth at full‑back.

Fans on social media have repeatedly asked why United continues to buy quantity rather than quality in defence, and many have called for immediate reinforcement of the back‑four. The club’s recruitment strategy has been a point of contention ever since Sir Alex Ferguson’s retirement.

Despite several managerial changes, the same themes – inadequate squad depth, especially in defence, and a lack of clear strategic direction – keep resurfacing. Carrick’s role cannot be evaluated in isolation; he inherits a squad assembled by the board and the scouting department, and he can only work with the players that are made available to him. Carrick’s interim tenure last season was impressive enough to earn him the permanent role, yet the nature of United’s performances this season has raised doubts.

In the Brighton game he made nine changes, a decision that left the team vulnerable after the initial two‑goal burst. After the match, Carrick accepted full responsibility, telling Sky Sports, “We can’t accept that as a group.

I take responsibility for it. The performance towards the end of the second half, that’s on me.” Critics argue that the blame should shift from the manager to the players, noting that constantly rotating managers does not solve the underlying squad issues. The defensive frailties were on full display: Yoro and Heaven struggled to cope with Brighton’s aerial threats, allowing Luka Vuskovic to win a header that was later finished by Pascal Gross.

In the third goal, Yoro was again caught out, highlighting a lack of experience and positional awareness. Full‑backs Dalot and Mazraoui also attracted criticism for their positioning and distribution, and the depth behind them remains questionable.

Fans have called for the acquisition of two high‑quality wing‑backs to provide balance and stability on the flanks. In attack, United have altered a successful formula from the previous season.

Last year, a relatively settled trio of Matheus Cunha on the left, Bryan Mbeumo centrally, and Amad Diallo on the right, with Benjamin Šeško as the impact substitute, produced a fluid rhythm. This season, Marcus Rashford’s return to the left side has disrupted that balance, and supporters have voiced concern that the change has dulled the team’s offensive edge. After the early burst against Brighton, United failed to generate consistent shots on target, and Rashford’s late effort that hit the near post was the only real chance to equalise.

Overall, Manchester United’s current predicament is a mix of fitness shortfalls, defensive inexperience, and a recruitment policy that has not delivered the needed quality in key areas. Until the club aligns its transfer strategy with a clear tactical vision and improves the physical conditioning of its squad, Carrick will continue to face scrutiny, but the responsibility for the deeper problems lies with the broader structure of the organization.
