Manchester United were 2-0 up at Old Trafford and still managed to turn the night into another ugly one. Shea Lacey's goal on his first start and an early strike from Mason Mount gave Michael Carrick exactly the platform he needed, but Brighton wiped it out and deepened the pressure around United's start. The most damaging part was not just the collapse itself. It was how little control United had once Brighton settled.
United's collapse after the fast start
Lacey scored after eight minutes on his first start for United, a moment that should have carried the story. Mount then made it 2-0 early on, and Old Trafford had every reason to expect a routine cup night.
Instead, Brighton grew into the game and United faded badly. Carrick's team failed to register another shot on target until the 76th minute, which is a brutal number when you have already built a two-goal lead at home.
Charalampos Kostoulas began the comeback, and Brighton then scored twice in four second-half minutes through Pascal Groß and substitute Maxim De Cuyper. Reports differ on the exact minute of De Cuyper's winner, with some placing it in the 69th, others the 70th, and others simply describing it as coming four minutes later. What is not in doubt is how quickly United lost the tie.
There is similar noise around how to label the exit, with some reports calling it a first-hurdle defeat and others describing a different round. The broader point is straightforward: United were knocked out after leading by two goals at Old Trafford, and the game got away from them far too easily.
RTÉ Sport reported that United had not lost at Old Trafford after going two goals up since 1976. Other reports phrase it more loosely as the first time in 50 years or over 50 years. Either description lands in the same place for Carrick, because collapses like this are rare in the club's home history and hard to brush off as a one-off.
Lacey's moment buried by the result
Lacey was among eight changes and still looked ready for the occasion. His goal after eight minutes gave United energy and, for a while, made the rotation call look bold rather than risky.
RTÉ Sport said: "Shea Lacey marked his first start with a goal a day after it emerged that 15-year-old talent JJ Gabriel had requested to leave". The wider significance was strong too, with Lacey becoming the first teenager to score on his first United start since Marcus Rashford in February 2016.
That should have been the headline from a domestic cup tie like this. Instead, it became a footnote because the team around him stopped functioning once Brighton started to push the game higher.
Carrick had also handed a rare start to Karl Darlow, who had not made a Premier League appearance this season before this tie. Leny Yoro had only two league appearances before this game as well. Rotation explains part of the fragility, but not all of it. United finished third in the Premier League last season, while Brighton ended up eighth, so a two-goal cushion at home still had to be managed better than this.
Brighton had also won four of their previous five visits to Old Trafford, so this was not some freak smash-and-grab. They have looked comfortable in this stadium before, and once United stopped threatening, the away side played like a team that expected chances to come.
Pressure grows around Carrick
Goal.com described the aftermath in blunt terms: "Michael Carrick is now facing immense pressure to save his job as the Red Devils' miserable start to the season continues following this historic collapse."
That pressure is understandable, even if it is still pressure rather than certainty over his future. United's recent league form before this tie was uneven, and this cup defeat added another layer because it came from such a winning position. A manager can survive a loss to decent opposition. Throwing away a two-goal lead at home, while producing almost nothing in response until the 76th minute, is harder to defend.
The most worrying part for United is that Brighton did not need a freak spell or a barrage of chances all night. They needed United to lose structure and belief, and once that happened the tie swung quickly.
Old Trafford started with a debut-story feel because of Lacey and a comfortable scoreline because of Mount. It ended with Brighton going through and Carrick facing another round of scrutiny after a defeat United had in their hands.
FAQ
Why is Michael Carrick under pressure after Manchester United lost to Brighton?
Carrick is under pressure because Manchester United threw away a two-goal lead at Old Trafford and went out of the Carabao Cup after losing control of the game. United did not register another shot on target until the 76th minute, and Brighton scored twice in four second-half minutes to complete the turnaround.
How significant was Shea Lacey's goal for Manchester United against Brighton?
Lacey scored after eight minutes on his first start for Manchester United, which should have been the story of the night. It was also a rare landmark, with RTÉ Sport reporting that he became the first teenager to score on his first United start since Marcus Rashford in February 2016.
Did squad rotation play a part in Manchester United's collapse against Brighton?
Rotation was part of the backdrop. Carrick gave a start to Karl Darlow, who had not made a Premier League appearance this season, and Leny Yoro had only two league appearances before the tie. That does not excuse losing from 2-0 up, but it helps explain why United looked less stable once Brighton settled.
