Gary Neville characterised Manchester United's recent derby defeat as a truly "bad day" for the side overseen by Michael Carrick, underscoring that the mounting pressure on the manager is intensifying after the Red Devils failed to capitalize on a numerical advantage against a ten‑man Manchester City at Old Trafford. The match began with a promising edge for United when Phil Foden was shown a red card early in the first half, leaving City with only ten players.

However, United were unable to translate that advantage into a decisive lead. The game was ultimately decided by a controversial winner from Erling Haaland, who slotted home in the dying moments to give City a 1‑0 victory. In the aftermath, the officiating body Pro Ref publicly admitted that an error had been made in the decision that awarded the winning goal.

Within hours of the final whistle, the organization confirmed that it had been in contact with Manchester United to acknowledge an "error of judgment". According to Pro Ref, the VAR protocol should have prompted an on‑field review because Enzo Fernández was in an off‑side position at the moment of the decisive play, a factor that could have nullified the goal.

Sky Sports News reported that United have since received an apology for the incorrect VAR call, adding another layer of frustration to an already disappointing result. While the controversy surrounding the goal has dominated headlines, Neville emphasised that United's inability to break down a reduced City side is a far more serious concern, especially given the team's ongoing struggles to control games. "Michael Carrick can be angry about the goal, but he should also be angry about the performance," Neville said during his appearance on the Gary Neville Podcast.

He went on to describe the final ten minutes of the match as "awful" from an experience perspective, noting that United had thrown everything they had at City – "the kitchen sink" – yet still found themselves on the receiving end of a goal in a pressure‑cooker situation. Neville also highlighted a broader issue that has emerged under Carrick's tenure: United's apparent difficulty in handling matches after an opponent is reduced to ten men. The Red Devils have now suffered three defeats in the past year when faced with a numerically disadvantaged opponent. The most recent of those was a 1‑0 loss to Everton last season after Idrissa Gana Gueye was sent off at Old Trafford.

The latest setback leaves United with just four points from their opening four Premier League fixtures, tying the club's poorest start to a league campaign in its history. Carrick's record after four games mirrors that of Benfica manager Ruben Amorim at the same stage of the previous season, a comparison that does not bode well for United supporters.

While acknowledging that it is still early in the campaign, Neville warned that the warning signs are already evident and that the pressure on Carrick is set to increase. "It was a bad day for Manchester United, it really was," he said.

"Losing a derby is already a shocking day – I've lost derbies myself, it's awful – but to not score a goal against ten men is not what I expected today. I expected goals from Manchester United." Neville continued, pointing out that United's performances have been uneven across the board. He cited the recent encounter with Ipswich Town as an example, noting that the visitors were dangerous for the majority of the match, creating several clear‑cut chances and potentially scoring two or three goals. "There are questions building," Neville added, suggesting that United's defensive frailties and lack of cutting edge are becoming increasingly apparent.

Looking ahead, United's next fixture is an away match against Fulham on Sunday, which will be broadcast live on Sky Sports. Neville believes this upcoming game will serve as a true test of Carrick's ability to steady the ship.

"Next Sunday against Fulham becomes a real pressure game now because obviously Fulham have not started the season that well," he said, implying that United must seize the opportunity to reverse their fortunes. In summary, the combination of a controversial VAR decision, a failure to exploit a ten‑man advantage, and a series of sub‑par performances has placed Michael Carrick under a growing cloud of scrutiny.

Neville's comments reflect a broader sentiment among United fans and pundits: the early season struggles cannot be ignored, and the manager must find a way to galvanise his squad before the pressure mounts any further. The Red Devils will need to address both their tactical approach and mental resilience if they hope to avoid a repeat of this "bad day" and to climb out of what currently stands as one of the toughest starts in the club's Premier League history.
