Manchester City left Old Trafford with three points.
The refereeing authorities have now acknowledged that the decisive goal should have faced a different VAR process.
That is the uncomfortable aftermath of a Manchester derby settled by Erling Haaland.
Haaland scored the only goal as 10-man City beat Manchester United 1–0, finishing in the second half after Phil Foden had already been sent off.
The goal was initially checked for offside before being allowed to stand following a lengthy VAR review.
The controversy did not disappear with the final whistle
Professional Game Referees, the body responsible for match officials in English football, later acknowledged an error in the handling of the incident and said referee Michael Oliver should have been advised to review it on the pitchside monitor.
The issue was not simply whether Haaland himself was in an offside position.
The debate centred on whether an offside-positioned City player had interfered sufficiently with a Manchester United defender in the build-up before Haaland finished at the back post.
VAR allowed the goal
Pro Ref’s later position was that the incident should have been sent back to Oliver for an on-field review.
That matters because this was not a marginal call buried inside a comfortable victory.
It was the only goal of the derby.
City had already been reduced to 10 men after Foden’s first-half dismissal, leaving Manchester United with a numerical advantage for most of the contest.
United could not turn that advantage into a goal.
Then Haaland struck. The flag went up. VAR intervened.
After the review, the goal stood.
City protected the lead to the final whistle and walked away with a 1–0 victory.
The result remains unchanged
Pro Ref’s acknowledgement does not remove City’s three points, rewrite the Premier League table or formally cancel Haaland’s goal.
But it does change the argument around how the decisive moment was handled.
For Manchester United, the frustration is obvious.
They lost a derby through a goal that the refereeing body now says should at least have been subjected to an on-field review.
For City, the controversy sits alongside a different story.
They played most of the match with 10 men, survived Manchester United’s pressure and still found the moment required to win.
That leaves the derby carrying two truths at once.
Manchester City produced a resilient away victory under difficult circumstances.
And the decisive goal is now attached to an acknowledged VAR error in process.
Haaland remains the scorer.
Manchester City keep the points.
But a derby that appeared finished at the final whistle has been reopened by the refereeing body’s acknowledgement that the decisive incident should have been handled differently.
For Manchester United, that acknowledgement changes nothing on the scoreboard.
For English refereeing, the harder question is what happens the next time one goal, one VAR call and one missed on-field review decide a match this big.
