Wednesday night gave the home end roughly ten minutes of something to enjoy. Manchester United fans boo frequently enough now that the noise barely registers as news, but this one had a clean, documented trigger: a 2-0 lead built inside the opening quarter-hour, dismantled by Brighton across the next hour, and a third-round exit that nobody in the ground had priced in at half past eight.
Shea Lacey scored in the eighth minute on his first start, becoming the first United teenager to do so since Marcus Rashford. Mason Mount made it two in the tenth. By the time Maxim De Cuyper finished a counter-attack to complete the turnaround, supporters were filing towards the exits with a chant that may have been aimed at the referee but landed just as easily on the players: "What the *ing hell was that?"*
Carrick did not argue with any of it.
Eight minutes of belief, then an hour of unravelling
The scoring sequence is short, and it tells the story without much help.
| Minute | Scorer | Score |
|---|---|---|
| 8' | Shea Lacey (Manchester United) | 1-0 |
| 10' | Mason Mount (Manchester United) | 2-0 |
| 45+1' | Charalampos Kostoulas (Brighton) | 2-1 |
| 65' | Pascal Gross (Brighton) | 2-2 |
| 70' | Maxim De Cuyper (Brighton) | 2-3 |
Carabao Cup third round, Old Trafford, 16 September 2026.
The defensive detail matters more than the timeline. Brighton's route back ran through Pascal Gross, 35, who controlled the middle of the pitch once United stopped pressing with any conviction. Gross took his equaliser after United again played the ball out from the back carelessly, with Diogo Dalot mishitting a clearance.
Luka Vuskovic's header dropped straight into the United box before that, with the centre-backs slow to react. The winner came from a counter down United's left, Diego Gómez and Charalampos Kostoulas raiding the flank before the cut-back found De Cuyper.
Three goals, three avoidable sequences. Carrick called the performance towards the end of the second half "unacceptable" and said the analysts would be rewatching the concessions.
Brighton, for their part, are becoming the season's most watchable side under Fabian Hürzeler — this comeback sits alongside a seven-goal match against Chelsea.
145 leads, one collapse: the number under the noise
The historical framing is what turned a cup exit into a genuine flashpoint.
- Since 2013, when Ferguson retired, United had taken a two-goal lead at Old Trafford on 145 occasions and never lost from that position.
- Only Sevilla and Everton had even salvaged a draw from 2-0 down at the ground in that span.
- The last outright home defeat after leading by two came in 1976, a 3-2 loss to Tottenham.
The cup route was supposed to be the safe one
United's previous League Cup campaign ended at Blundell Park against Grimsby Town, a result that still functions as shorthand for the club's low point. A year on, the exit is less absurd on paper — Brighton are a Premier League side in good form — and arguably more troubling, because the manner of it was self-inflicted rather than freakish.
Erik ten Hag used the domestic cups to bank silverware while the league form sagged. That escape route is one competition narrower for Carrick already, and the club's last knockout win of any kind came 19 months ago, against Leicester City in the FA Cup.
Manchester United fans boo the manager they were happy to have
The uncomfortable part is who was on the receiving end.
Carrick took over in January 2026 after Ineos dismissed Ruben Amorim, with United sixth on 31 points and 17 behind Arsenal. He immediately delivered wins over Manchester City and Arsenal, which bought him a level of goodwill that most Old Trafford managers never see.
Nine months later, United sit 13th in the Premier League after four matches and are out of the Carabao Cup at the first attempt.
Carrick's response at full time was to absorb it rather than deflect:
> "I totally understand the feelings of the supporters. We have to accept it. I totally accept it. It's on me ultimately: as a team, what we look like, how we play and what results you get. I take that. I'll take the praise, I'll take the criticism and the upset."
He also acknowledged the mood is running ahead of the result itself. "We've gone out of the cup and the feeling around the place feels bigger than that," he said. "I'll be honest about that, that's how it feels, but it doesn't have to be like that. If we win football matches again, it can go in a different direction."
That is a fair read of the room. The jeers were not really about a cup tie. They followed a home derby defeat to a ten-man Manchester City four days earlier — a match in which refereeing chiefs subsequently apologised to United over an offside in the build-up to Erling Haaland's winner — and they arrived in a week when academy forward JJ Gabriel asked to leave the club.
A teenager kissed the badge after scoring on his first start. Another one was reportedly trying to get out. Old Trafford noticed both.
Fulham away, and a narrowing margin
Sunday's trip to Fulham is the last fixture before the international break, which is the worst possible scheduling for a club in this mood. A defeat means a fortnight of silence in which the discussion writes itself; a win resets the conversation cheaply.
Carrick knows the arithmetic. "We have a big game on Sunday that we have to prepare for," he said. "We want to win and want to win quickly."
The structural question he has not yet answered is why a side that beat City and Arsenal in his first weeks concedes three goals in 25 minutes from a position of total control. Slack defending contributed to all three Brighton goals, and several players visibly eased off while the game was still there to be won. That is not a tactical problem so much as a standards problem, and standards are the thing a crowd can hear from the stands.
Carrick said he takes responsibility. The supporters have taken him at his word — which is precisely why the reaction at the whistle was aimed at everyone on the pitch, and at the man walking behind them.
