The harsh reality of Sunday's 1-0 derby defeat to 10-man Manchester City at Old Trafford highlighted several areas where Michael Carrick’s Manchester United still need to improve.
Manchester City manager Enzo Maresca was able to adapt tactically and manage his side to all three points despite playing with 10 men for 76 minutes, with their squad depth proving valuable in the second half. Meanwhile United are left contemplating the massive gulf in quality separating the two rivals.
Striver.Football identifies five ways the defeat exposed the massive deficiencies in United’s squad, recruitment, and tactical execution.
1. Manchester United’s Bench Depth Falls Short of Manchester City’s
Nothing illustrated the contrasting landscapes of the two clubs better than the late-game substitutions. Trailing in the final ten minutes, Carrick turned to Joshua Zirkzee, a player who had been linked with a departure from United during the summer after scoring just 9 goals in 76 appearances, to save the derby. Zirkzee’s most notable contribution was an overhit cross.
Conversely, Maresca introduced £65 million summer signing Iliman Ndiaye at half-time to bolster City’s defensive output on the right wing.
It was Ndiaye who pounced on Patrick Dorgu’s miscued header, dispossessing United to initiate the sequence that led to Erling Haaland’s winning goal.
It highlighted City’s ability to introduce a different profile of player from the bench, while United turned to players who had struggled to make a consistent impact.

2. United’s Midfield Balance Remains a Concern
City’s midfield engine room of Elliot Anderson and Enzo Fernandez cost a combined £241 million. In contrast, United’s central pivot was anchored by Youri Tielemans, who cost just £35 million and academy graduate Kobbie Mainoo.
While Mainoo produced a commanding individual display, winning crucial duels against Anderson and setting up Marcus Rashford's side-netting effort, his performance highlighted internal contradictions.
Under previous head coach Ruben Amorim, United were previously reported to be open to offers for Mainoo at a significantly lower figure than some reported valuations of the midfielder.
Meanwhile, summer signing Andrey Santos, who cost £50 million, has managed just 42 minutes across United’s last four matches, raising fresh questions about recruitment priorities.
3. Patrick Dorgu Exposes United’s Left-Back Vulnerability
An injury to Luke Shaw thrust Patrick Dorgu into the left-back role, a position he had not played once during pre-season.
Dorgu’s lack of defensive positional awareness was ruthlessly exploited for City's winner. Swept out of position while tracking the ball, Dorgu drifted all the way across to right-back, leaving Lisandro Martinez exposed in a two-against-one situation at the far post.
United’s decision not to pursue a natural, proven left-back like Lewis Hall has quickly backfired.

4. Carrick’s Substitutions Raise Questions About United’s Game Management
Carrick’s game management came under severe scrutiny as United chased the match. Following Haaland’s 60th-minute goal, it took Carrick another seven minutes to introduce Benjamin Sesko, despite the Slovenian striker looking like a logical half-time change to disrupt City's low block.
Furthermore, withdrawing Tielemans compromised United’s midfield balance, while Marcus Rashford, who had been United's liveliest attacker was substituted instead of a struggling Matheus Cunha.
The Red Devils failed to generate high-quality chances until the 95th minute, when Bruno Fernandes created a rare opening for Bryan Mbeumo, only to be denied by Gianluigi Donnarumma.
5. United Still Struggle to Break Down Deep Defensive Blocks
Despite playing against 10 men for over 70 minutes following Phil Foden’s 23rd-minute red card, United’s attack was static, predictable, and devoid of sharp passing lanes.
Maresca correctly recognised at half-time that denying United transition space would neutralise their primary threat.
The defeat now means United under Carrick (and previously under Amorim) have repeatedly failed to capitalise when opponents are reduced to 10 men, having suffered similar setbacks against Newcastle and Everton over the past year.
Until Carrick develops more effective solutions against stubborn mid-blocks, questions will remain over whether United have enough attacking variety to sustain a title challenge.
Striver Verdict: Manchester United Still Have Work to Do
Michael Carrick deserves credit for stabilizing the ship and steering United back into Champions League football last season, but this derby defeat provides a sobering reality check.
While controversy surrounds the VAR error on Erling Haaland’s goal, the VAR controversy should not obscure United's difficulties in breaking down a 10-man defensive block for more than 70 minutes.
Bound by Glazer-era financial burdens and inconsistent transfer market execution, United simply do not possess the squad balance, midfield depth, or tactical variance required to challenge for the Premier League title.
