Manchester United’s latest Manchester derby defeat has exposed two major weaknesses that Michael Carrick can no longer afford to ignore.
The 1-0 loss to Manchester City at Old Trafford was frustrating enough for United supporters, but the manner of the defeat made it even more painful. City played with 10 men for more than 70 minutes after Phil Foden was sent off, yet United still failed to take advantage.
Erling Haaland eventually scored the decisive goal, while United struggled to create enough clear chances despite their numerical advantage.
For captain Bruno Fernandes, the frustration was obvious. United’s leader demanded more from his teammates, while two players in particular came under heavy scrutiny: Diogo Dalot and Patrick Dorgu.
For Cambodian football fans following the Premier League, this derby highlighted a familiar problem at Old Trafford: United may have improved their attacking options, but defensive consistency remains a serious concern. 🔴
Manchester United’s Two Weakest Links Revealed
The defeat against City did not simply expose one bad performance. It highlighted structural problems that have been visible during the opening weeks of the season.
1. Patrick Dorgu’s Defensive Problems
Patrick Dorgu has plenty of physical ability, but his defensive positioning remains a concern.
Against City, the young full-back was involved in one of the most important moments of the match when his positioning ultimately played a role in Haaland being judged onside for City’s winning goal.
The goal initially appeared to be offside, but VAR determined that Dorgu’s position played Haaland onside.

He possesses pace, aggression and the ability to contribute going forward, but elite Premier League defenders are judged on concentration and positioning as much as athleticism.
Against City, one positional mistake was enough to change the game.
2. Diogo Dalot Continues to Frustrate
The second major concern is Diogo Dalot.
Dalot has been a regular presence in United’s defence for several seasons, but his performances have increasingly raised questions about whether he should remain an automatic starter.
His display against City was heavily criticised, with The Sun’s player ratings giving both Dalot and Dorgu a low score after United’s defeat.

Instead, United need greater reliability from their full-backs.
When facing elite opponents such as City, full-backs must know when to press, when to hold their position and when to protect the space behind them.
United have repeatedly struggled with those details.
And against a striker like Haaland, even the smallest defensive error can become decisive.
Bruno Fernandes’ Frustration Is Becoming Impossible to Hide
The Manchester United captain demands more
Bruno Fernandes is not a quiet captain.
The Portuguese midfielder has always been vocal on the pitch, and his willingness to demand higher standards from teammates is one of the defining characteristics of his leadership.
That was again visible during the latest Manchester derby.
United’s captain was visibly frustrated as his team struggled to exploit City’s red card advantage. The problem was not a lack of opportunity — it was a lack of execution.
United had more than an hour against ten City players but still managed only limited clear-cut opportunities.
That is exactly the type of situation that drives Fernandes crazy.
The captain knows United should have taken control of the match.
Instead, City looked more organised and eventually found the winning goal.
A Teammate Had a Night to Forget
Bruno’s frustration also reflected the performance of his teammates.
While Fernandes himself did not produce his best derby performance, United’s problems went much deeper than their captain.
The biggest issue was that too many players failed to produce when the opportunity was there.
United had the numerical advantage. City had the defensive pressure. Yet United could not consistently break them down.
That makes the criticism of Dorgu and Dalot particularly significant.
The two full-backs were expected to provide width, defensive security and support for the attack. Instead, United’s wide areas repeatedly became vulnerable.
United’s Attack Was Also Toothless
It would be unfair to blame everything on the full-backs.
Manchester United’s attacking players must accept responsibility too.
Marcus Rashford and Kobbie Mainoo both hit the woodwork, while Bryan Mbeumo had a late opportunity that could have changed the result. But United generally struggled to test Gianluigi Donnarumma consistently.
Matheus Cunha also failed to make the required impact.
Benjamin Sesko and Joshua Zirkzee were introduced from the bench, but neither could provide the breakthrough Carrick desperately needed.
This is why the defeat feels bigger than one result.
United had a one-man advantage for most of the match.
They still lost.
Haaland Punishes United’s Mistake
Manchester City’s winning goal made the defensive criticism even more painful.
Haaland finished in the 60th minute after City worked the ball into a dangerous position.
United believed the Norwegian striker had been caught offside, but VAR eventually confirmed the goal because Dorgu’s positioning played Haaland onside.
One defensive detail decided the Manchester derby.
That is the level Manchester United must reach if they want to challenge the Premier League’s strongest sides.
Michael Carrick Has a Serious Selection Problem
Should United change their full-back options?
Michael Carrick now faces an important decision.
Dorgu remains a young player with considerable potential, while Dalot offers experience and versatility.
But potential and experience are not enough if the same defensive problems continue.
United’s summer recruitment improved several areas of the squad, yet the full-back positions remain vulnerable.
The wider squad audit conducted before the season also highlighted defensive areas as positions where United still needed improvement.
Carrick therefore has two choices.
He can continue trusting the current options and hope their performances improve.
Or he can make more aggressive selection decisions.
For a club targeting Champions League football and major trophies, the second option may eventually become unavoidable.
Bruno Fernandes Cannot Fix Everything
One of the biggest challenges for Manchester United is that Fernandes is often expected to solve too many problems.
He is the captain.
He creates chances.
He scores goals.
He presses.
He demands standards.
And he frequently tries to organise teammates during matches.
But even Bruno cannot compensate for structural weaknesses across the team.
His frustration is understandable, but United need more players who naturally share his intensity.
A successful Manchester United side cannot depend on one captain constantly demanding standards from everyone around him.
The entire team must reach that level.
What Happens Next for Manchester United?
The Manchester derby defeat leaves United with plenty of questions after a difficult opening period.
They have now shown flashes of quality but remain inconsistent.
The attack has potential.
The midfield has improved.
The squad has more depth.
But defensive reliability remains a major concern.
Dorgu needs to improve his positional awareness. Dalot needs greater consistency. The centre-backs need better protection from midfield. And the entire team must learn how to control matches when they have a numerical advantage.
Final Verdict
Manchester United’s 1-0 defeat to Manchester City was more than another derby loss. It exposed weaknesses that Michael Carrick must address quickly.
Patrick Dorgu’s positioning and Diogo Dalot’s inconsistent defensive work have become major talking points, while Bruno Fernandes’ visible frustration demonstrates how much pressure is already building inside the squad.
City showed the mentality United lacked.
Playing with ten men for most of the match, Enzo Maresca’s side remained organised, defended with discipline and eventually found a way to win.
United had the advantage.
City had the result.
For Carrick, that is the clearest warning of all.
If Manchester United want to compete with the Premier League’s best, they cannot afford to waste opportunities like this — and they certainly cannot continue making the same defensive mistakes. 🔥
