One of world football's most fiercely contested rivalries resumes Manchester United host Manchester City in a Premier League clash at Old Trafford from 4.30 PM BST on Sunday, 13th September.

With both Michael Carrick and Enzo Maresca forced to plug severe injury list gaps, a cohort of 6 breakout stars aged 23 and under are uniquely positioned to tip the scales in this blockbuster derby.

Striver.Football lists them, as we reveal in detail why you should be on the lookout for them.

Manchester United 

Kobbie Mainoo (21) — Central Midfielder

Stats (2026–27): 89% Pass Accuracy | 0.7 Key Passes per 90 | 2.8 Tackles and Interceptions / 90 | 1 Assist

The local midfield talisman shoulders a monumental defensive load alongside Youri Tielemans on Sunday with Manuel Ugarte and Carlos Baleba both ruled out through injury. 

Tasked with controlling tempo, Mainoo operates in tight half-spaces to break lines and carry transition play safely away from intense presses. His elite positional spatial awareness in Carrick's dual pivot will be the primary anchor required to bypass City's high pressing lines.

Patrick Dorgu (21) — Left Midfielder / Left-Back

Stats (2026–27):1 Assist | 1.8 Interceptions and Tackles / Game

Fresh off a crucial goal during United's stunning 2–0 derby victory in their last head-to-head encounter at Old Trafford, the high-octane star provides a dynamic wide threat. 

Dorgu overloads channels vertically, arriving late into the penalty box to create shooting advantages. His intense bursts down the flank will look to compromise City's full-backs on counter-attacks.

Leny Yoro (20) — Center-Back

Stats (2026–27): 91% Pass Accuracy | 4.2 Clearances / Game

Following defensive injuries to Matthijs de Ligt, Yoro's tactical recovery pace is under intense scrutiny. 

Relying on long-stride acceleration to lock down deep zones when chasing over-the-top balls, the young Frenchman's aerial dueling inside the 18-yard box against Erling Haaland will dictate United's backline stability, having impressed against Sabah in midweek.

Manchester City

Nico O'Reilly (21) — Left-Back / Central Midfielder

Stats (2026–27): 86% Pass Accuracy | 2.5 Aerial Duels Won

The academy graduate has been a revelation this season under Maresca, proving his big-game pedigree by seamlessly morphing from midfield into an inverted full-back hybrid. 

Fully recovered from a recent back issue, O'Reilly drops deep dynamically to act as a third midfielder during possession phases, creating overloads in United's central engine room while opening space wide.

Abdukodir Khusanov (22) — Right-Back / Center-Back

Stats (2026–27): 88% Pass Accuracy | 3.1 Successful Challenges

The rapid Uzbek defender has solidified his role as one of the league's quiet achievers.

Tasked with starting at right-back to counter United's quick wingers, Khusanov uses immense recovery acceleration to completely shut down wide threats in isolation, offering vital insurance against direct breaks.

Elliot Anderson (23) — Attacking / Central Midfielder

Stats (2026–27): 93% Pass Accuracy | 1.2 Fouls Drawn / Game

City's marquee summer signing is expected to break into Sunday's starting eleven following a masterful passing display against Coventry.

Anderson brings elite tactical tempo control, specializing in heavy ball retention, crisp horizontal distribution, and high pass-completion numbers deep within enemy territory.

Key Lessons Ahead of Sunday's Derby

Mainoo vs. O'Reilly Central Overload: The central midfield clash between Mainoo’s defensive positioning and O'Reilly’s inverted midfield movements will be decisive. If O'Reilly successfully steps inside to create a numerical 4v3 in possession, Mainoo will need disciplined lateral support from United's starting right winger to prevent City from dominating the half-spaces.

Yoro’s Box Defense Against Haaland: Leny Yoro’s 4.2 clearances per game reflect his comfort in sweeping deep, but facing Erling Haaland’s physical presence inside the 18-yard box requires raw strength. Yoro must combine timing and long-stride recovery to prevent Haaland from isolating him in 1v1 central aerial duels.

Dorgu's Counter-Attacking Channels: Patrick Dorgu’s memory of his goal in the previous Old Trafford derby makes him a major psychological weapon. His vertical runs behind City's high line will directly test Khusanov’s recovery speed, making the right-flank transitional duel one of the match’s absolute flashpoints.
