After Manchester United lost 0-1 to 10-man Manchester City in the Manchester Derby at home, The Athletic reported that Manchester United's loss was emblematic of their failed summer transfer window, with the club now facing internal and external challenges. Manchester City, by contrast, remains financially strong and continues to bolster its squad.

The report highlighted that Carrick's decision to bring on Zirkzee late in the match, while Maresca brought on Ndiaye at halftime to secure victory, underscored the contrasting situations of Manchester United and Manchester City.
Manchester United attempted to sell Zirkzee throughout the summer, while Manchester City signed Ndiaye from Everton for £65 million and pivoted to him after failing to pursue other targets in the final week of the transfer window.
Zirkzee is a technically gifted Dutch international who has featured in major tournaments for his country. However, before Carrick brought him on for Rashford in the 90th minute with seven minutes remaining, he had scored only 9 goals in 76 appearances for Manchester United. He was expected to leave at the start of summer, but Manchester United failed to generate sufficient interest, and the move never materialized.
Ndiaye was also targeted by Tottenham Hotspur, but Manchester City moved first. In the Manchester Derby , Maresca brought him on after Phil Foden was sent off in the first half, hoping the right winger could provide additional defensive cover.
Ndiaye won possession following a clearance error and initiated the attack that ultimately led to Haaland's winning goal. Zirkzee's most notable contribution was an overhit cross.
Many will hope he delivers greater impact this season, though Ndiaye's form may eventually decline. The larger issue is that Manchester City has strengthened Guardiola's squad under Maresca through financial resources and strategic acquisitions, while Manchester United's backing for Carrick in this window has been considerably more limited.
Notably, visiting teams have suffered 50 red cards at Old Trafford in the Premier League, yet only two have won: Everton in November 2024, and Manchester City today, with both victories featuring Ndiaye on the pitch on the winning side.
The midfield tells a similar story. Manchester City signed Elliot Anderson and Enzo from Nottingham Forest and Chelsea respectively this summer for a combined £241 million. Manchester United's midfield investment, by contrast, totaled just £35 million in the same period – Youri Tielemans' release clause from Aston Villa.
Tielemans' midfield partner Mainoo, an academy graduate, cost nothing in transfer fees, yet his performance in this match—particularly his superior showing in direct duels against Anderson, including one tackle that created a shooting opportunity for Rashford—suggests he is worth well over £100 million. However, under Amorim's tenure, the club was willing to consider offers significantly below that valuation.
Equally significant, this latest Manchester Derby took place amid fan protests both outside and inside the stadium, prompting a reassessment of how differently the two clubs' ownership structures have impacted performance. Manchester City has benefited from investment, while Manchester United has been burdened by Glazer family debt and costly transfer missteps, factors that have shaped minority shareholder Ratcliffe's strategy over the past two years.
Whether Manchester United should have spent within its means this summer, and on whom, remains contentious. The club will release its Q4 financial report on September 23, which should provide clarity. Can more money still be spent? A clearer picture will emerge soon.
Has Manchester United deployed its existing resources wisely? Luke Shaw's minor injury and absence from this match directly exposed the team's left-back vulnerability. Dogu was unexpectedly deployed at left-back, a position he had not tried during pre-season. In the build-up to the goal, he ventured to the right flank and was caught out of position defensively, leaving Lisandro Martínez in a two-on-one situation on the far side.
Manchester United had previously considered signing Newcastle United left-back Lewis Hall before pursuing Omari Kellyman from Chelsea. The club also completed the signing of midfielder André Santos for an initial fee of £48 million, a move that sparked debate about the Red Devils' transfer priorities. Santos joined from Chelsea. After losing away to promoted Hull City in the opening match, he has featured for just 42 minutes across his last four games and did not get a chance to play in the Manchester Derby.
Manchester City's winning goal should not have stood; PGMOL later acknowledged it was a serious error.
But even if Manchester United had drawn 0-0, these questions about the squad would persist. After Foden's red card, Manchester City played with ten men for 70 minutes, yet Manchester United still failed to break down their defense.
Carrick's Champions League qualification last season earned him considerable credit. When he took over from Amorim in January, that goal seemed distant. However, compared to Manchester City and other coaches, he operates with less public goodwill due to his limited managerial experience.
His substitutions in this match did not pay off.
After Haaland scored in the 60th minute, Sesko came on only 7 minutes later. Bringing him on at halftime would have seemed more prudent. Moreover, after Tielemans departed, Manchester United's balance was disrupted. Rashford was also performing better than Cunha at that point, yet Cunha played the full match.
Manchester United's only genuinely clear-cut chance came in the fifth minute of added time. Bruno Fernandes delivered a through ball for Mbeumo, who had a shooting opportunity, but Donnarumma made the save. Mainoo was again involved in the attack.
For much of the second half, Manchester United's attack lacked movement as Manchester City sat deep. Manchester United again exposed their recurring difficulty in breaking down low blocks, with their passing lacking the accuracy and fluidity needed.
Against a team with a numerical disadvantage, they seemed short of ideas. In the past year, Manchester United has lost to Newcastle United under Carrick and to Everton under Amorim while the opponents played with one fewer player. Maresca even reminded his players at halftime that without the transitional space Manchester United typically exploits, the match would prove difficult.
This will likely be a persistent challenge for Carrick. The pace of this team's transformation is destined to be considerably slower than if more comprehensive changes had been implemented during the summer transfer window.
