The Manchester derby and Manchester United's 70 minutes with a man advantage

In the 23rd minute at Old Trafford, Phil Foden was sent off. Manchester City had to play the remaining 70 minutes with ten men. The final score was 1-0 to City. Across a spell with a man advantage lasting nearly three quarters of the match, Manchester United produced only two shots against the woodwork, from Kobbie Mainoo and Marcus Rashford, plus one stoppage-time effort saved by Gianluigi Donnarumma after Bryan Mbeumo's strike. That was the entire sum of what the home side managed against a defence that had lost a player very early.

A derby like that is usually remembered for Erling Haaland's controversial goal and the whistle. I have watched the footage of this match three times, and each time I stopped at the same passage: from the 30th minute to the 45th. United circulated the ball from the left flank to the right, then played it back into midfield. The ball passed through six players, and not one of them stood in the space between City's two lines. The most worrying thing about United in the derby was that they had no player to occupy the space ten-man City deliberately left open.

The decisive event came from the VAR room and was publicly confirmed afterwards. England's referees' chief Howard Webb admitted the officials were wrong to allow Haaland's goal from an offside position. That is a formal apology, the kind of statement rarely issued in the Premier League, and it was enough to pull almost all public attention towards the referees.

Michael Carrick responded the way a man used to pressure does. He said the apology does not mean much, that the error could not be allowed to affect the rest of the season. He stressed that this defeat does not mean a big and huge problem has suddenly appeared, and added that perhaps the law of averages will hand his team one or two favourable decisions in the coming weeks. That phrasing keeps him inside the governing body's disciplinary rules, avoids attacking the referee's integrity, but also declines to take responsibility in place of the defeat.

What happened around the derby is the more troubling part. Earlier, United were knocked out of the League Cup in the first round. After the derby, they lost 3-2 at home to Brighton, having led by two goals. It was the first time Brighton had won at Old Trafford in 50 years, and the first time Carrick had suffered back-to-back home defeats since taking the head coach job last January. Before that, his side had twice let 2-2 draws slip after leading against Everton. This Sunday they travel to Fulham.

To play against ten men, an opponent must choose between two routes: drop the block deep and concede the entire area in front of the 18-yard box, or keep the structure and accept gaps in the two wide channels. City chose the first route. They built a low block, sealed the central corridor, and let United hold the ball in areas that carried no threat. That was a deliberate choice by a team that knew it was ahead, not a panicked reaction.

Against a block like that, the route to goal narrows to three: runs from the second line into the pocket between centre-back and full-back, early crosses before the block can turn, and long shots that force the goalkeeper to work. United managed part of the third route. Mainoo and Rashford put the ball against the woodwork. On the other two routes, they produced almost nothing of note.

People are good at spotting a midfield's mistakes, and better still at spotting a mistake before the ball rolls. United's mistake in the derby lay in preparation. The starting XI contained no player who lives between the opponent's two lines, and no one capable of receiving with his back to goal and turning. When Foden was dismissed in the 23rd minute, Carrick had to change the attacking structure with nearly a quarter of the match already gone. He had no contingency for that scenario, because nobody prepares to play a man up for 70 minutes in a derby.

The second problem is more serious, and it has repeated often enough to become a pattern: managing a game while ahead. United led Brighton by two and lost 3-2. They twice led Everton and were pegged back to 2-2. This kind of deviation does not depend on the scoreline of one particular match; it depends on how the collective reacts when it holds the advantage. Tactics are not a diagram on a board, but a habit repeated over 90 minutes. This team's habit, when leading, is to slow the tempo, pass sideways more often, and hand control of central areas to the opponent.

Space is the only thing that cannot be bought in the transfer market. You can buy an attacking midfielder, but you cannot buy the habit of occupying space in the 75th minute while defending a one-goal lead. That comes only through coaching, repetition and match-by-match verification.

My own match-watching experience from the 2026 World Cup offers a similar method. Analysing France's 4-3 win over Argentina, I counted Lionel Messi's touches in the attacking third: 23, his lowest across five matches at that tournament. The conclusion was not that Messi played badly, but that the space in front of him had been cleared in advance by Didier Deschamps. With United in the derby, the count produced the opposite result. The attackers touched the ball constantly in the area in front of the 18-yard box, but almost nobody touched it between the lines. Holding the ball in the wrong area does not create chances.

One clarification on data: the post-match reports do not provide expected goals, passes allowed per defensive action, or detailed possession figures. Every conclusion above is drawn from footage and specific passages of play, not from a statistical model. That is a methodological limitation, and I state it so readers know how much certainty each judgment carries.

Howard Webb's apology, in sporting terms, fixes nothing. Once a match has ended there is no mechanism to restore points. Referees resemble the editor of a match: they decide which goals stand, but not which team creates chances. United lost the derby because they played 70 minutes a man up without scoring.

At Old Trafford, crises escalate very quickly and narratives turn even faster. This is an inherent feature of a place watched far more closely than its actual competitive standing warrants. Framing the issue around the killer instinct of previous generations draws more on nostalgia than on data. That instinct is not an innate quality; it is the product of a system that knows how to create chances at the right moment.

The summer of 2026 taught me that a mid-table club buys out of fear, not out of a plan. The same holds in reverse: a big club acting out of fear will also act wrongly. If United's leadership turns this run of results into a personnel crisis, they will repeat a familiar mistake, treating symptoms instead of structure.

Fulham is the pivot of this phase. The two indicators worth tracking are not the scoreline, but the number of chances created from between the opponent's lines, and how the team protects the ball while leading in the second half. A team with character does not change with the score; it changes with how it faces adversity. The derby has not yet told us United's character under Carrick. The next match might.
