Manchester United’s embarrassing defeat to Brighton has once again put the spotlight on Michael Carrick, but the issues at Old Trafford extend far beyond the man on the touchline. United stormed into an early 2-0 lead within the first ten minutes of Wednesday’s Carabao Cup tie, only to see that advantage evaporate as they eventually fell 3-2, bowing out of the competition for the second straight year and enduring a chorus of boos from their own fans.

It was a historic reversal. In the past half‑century, United had never lost a home game after taking a two‑goal lead – they had won 143 of the previous 145 such encounters. After Mason Mount’s second‑minute strike, the Red Devils failed to register another shot on target until the 76th minute, highlighting a dramatic drop in attacking intent. The loss has placed Carrick under intense scrutiny just months after his interim spell earned him a permanent contract.

Last season he guided United to 12 wins, three draws and two defeats from 17 games – a respectable 70.6% win ratio. This campaign, however, tells a different story: two victories, one draw and three losses from six matches, a win percentage that has slipped to roughly 33%.

The club now mirrors its joint‑worst start to a Premier League season after four fixtures, and the early cup exit has stripped away one of the few realistic avenues for silverware. So what is really going wrong at Old Trafford?

A key symptom is the lack of urgency on the pitch. United rank 14th in the league for total distance covered – 449.1 kilometres – but their figures tumble when intensity is examined.

They are 18th for total sprints (379), 19th for high‑speed runs (1,364), and similarly low for sprints and high‑speed runs per kilometre covered. In plain English, the team is moving the ball but not moving it quickly enough to press, recover or defend transitions effectively. Brighton exposed this deficiency starkly.

United made nine changes from the side that had featured in the Manchester derby, inserting several players who had spent much of the previous game on the bench. Brighton, meanwhile, also altered six personnel, including four debutants, and appeared fresher and fitter. Former player Jamie Redknapp remarked on United’s physical condition, saying, "They didn't look fit enough.

I saw too many players not running back or not looking fit enough." A specific example was Leny Yoro’s recovery after Brighton’s third goal. Rather than sprinting back to challenge, he was seen jogging, allowing the opposition to consolidate the lead. When a team cannot match its opponents in intensity, it is forced to defend larger spaces and spends longer periods without possession, a scenario that played out repeatedly against the Seagulls.

The squad turnover this summer also raises questions. United brought in seven permanent signings and four loanees, while 13 players departed permanently and ten more went out on loan. The bulk of the spending targeted midfield and attack – roughly £85 million on the likes of Youri Tielemans and Andrey Santos – with striker Carlos Baleba, a £70 million acquisition, still watching from the stands.

Transfermarkt values the first‑team squad at about £791.2 million, the fifth‑highest in England, but the distribution of that value is uneven. Attackers account for £317.2 million, midfielders £249.9 million, and the defensive unit only £193.8 million, suggesting a relative under‑investment in the back line. Defensive frailties were on display against Brighton. United fielded an inexperienced centre‑back pairing of Leny Yoro and Ayden Heaven, offering limited options at full‑back.

Fans voiced frustration on social media, asking why the club continues to buy quantity over quality and demanding immediate reinforcement of the defence, especially wing‑backs who can provide both solidity and width. The criticism is not limited to the players. Many supporters argue that the club lacks a coherent long‑term plan since Sir Alex Ferguson’s retirement. The board’s recruitment choices have left Carrick with a squad that, on paper, is valuable but on the pitch is unbalanced.

While the manager is accountable for tactics and selections, he can only work with the personnel assembled by the hierarchy. Carrick’s interim tenure last season was impressive enough to earn him the full‑time role, yet the nature of United’s recent performances is causing alarm.

His decision to make nine changes for the Brighton game was heavily questioned when the team’s early dominance quickly unraveled. 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." Beyond the tactical tweaks, the underlying issues include a lack of cohesion in defence, insufficient depth in quality wing‑backs, and an attacking setup that has been altered from a relatively stable formation last season.

Previously, United operated with Matheus Cunha on the left, Bryan Mbeumo centrally, and Amad Diallo on the right, with Benjamin Sesko as a reliable target man. The introduction of Marcus Rashford on the left flank has sparked debate among fans, who wonder whether this change has disrupted the team’s rhythm. The statistical evidence supports the narrative of a side lacking intensity.

United’s low ranking in sprints and high‑speed runs indicates a failure to press aggressively, allowing opponents to dictate play. When combined with a defence that is both inexperienced and thin on depth, the result is a team that concedes space, struggles to regain possession, and ultimately loses games that it should dominate. In summary, Manchester United’s recent woes are a product of several intertwined factors: a squad that, despite a high overall market value, is imbalanced with under‑investment in defence; a fitness and intensity deficit that hampers the team’s ability to press and transition; and a managerial situation where Michael Carrick is caught between the expectations of the board, the demands of a demanding fan base, and the reality of a roster that may not provide the tools he needs.

Until the club addresses these structural problems – whether through smarter recruitment, improved conditioning programmes, or a clearer strategic vision – the Red Devils are likely to continue stumbling in both cup and league competitions.
