Kobbie Mainoo, 21, was outstanding again as Manchester United beat Sabah 4-0 in the Champions League on Thursday, the third straight match in which he has been United’s standout midfielder since a difficult return from a World Cup where he didn’t play a single minute.
That run of form, against Ipswich, Everton and now Sabah, has put Mainoo firmly back at the centre of Michael Carrick’s plans ahead of Sunday’s derby against Manchester City at Old Trafford. It is a striking turnaround for a player who was an unused substitute all the way to England’s semi-final exit against Argentina and then didn’t even make the bench for the third-place play-off against France, with the FA citing an unspecified injury.
A lost summer, physically and mentally draining
Mainoo was invariably the first England player to leave the stadium after matches at the World Cup, walking through the mixed zone with the same impassive expression regardless of the result, according to the Guardian. Thomas Tuchel consistently preferred Elliot Anderson and Declan Rice in the deeper midfield roles, with Reece James, Jude Bellingham, Jordan Henderson, Morgan Rogers and Nico O’Reilly all used ahead of him at various points too.
The tournament run took its toll regardless of minutes played, given the travel and training and the demand to stay switched on while waiting. Mainoo reported late for United’s pre-season as a result, playing only the final half-hour of the club’s friendly against Milan before starting the campaign as a substitute at Hull, coming on with United already 2-0 down.

The numbers behind the resurgence
Since that afternoon at Hull, Mainoo has been United’s most reliable presence in midfield, and the underlying numbers explain why. Across his last three appearances he has attempted 211 passes and completed 201, a level of ball security that stands out given how often he demands the ball in dangerous areas and how much risk he takes once he has it.
| Metric | Passes Attempted | Passes Completed | Defensive Contributions |
| Last 3 games | 211 | 201 | Game-high 15 vs Ipswich and Everton |
He is improving out of possession too, and it’s the quick feet and hip-shaking changes of direction that stand out most, simultaneously unsettling opponents and shifting United’s angles of attack.
Why the derby comes down to Mainoo’s midfield
United spent £155m reshaping their midfield over the summer, bringing in Youri Tielemans, Andrey Santos and Carlos Baleba, though Baleba is yet to feature because of injury. Even with that outlay, it’s Mainoo who has reasserted himself as Carrick’s first choice, and the derby selection question is really about who plays alongside him in front of the back four.
Carrick is expected to start Tielemans next to Mainoo with Bruno Fernandes as the third midfielder, up against an Anderson, Enzo Fernández and Rayan Cherki trio for City. United supporters have already adapted the lyrics to Billy Ocean’s Love Really Hurts Without You to make the point that this team simply doesn’t function without him.
Andrey Santos’ arrival has only sharpened the competition in United’s engine room, even if Mainoo currently looks unmovable.
From frozen out to first choice
It’s worth remembering how recently this looked improbable. Ruben Amorim couldn’t fit Mainoo into his 3-4-2-1 system and didn’t trust him defensively, meaning he failed to start a single Premier League match under the Portuguese last season.
His first league start of that campaign didn’t come until January against City, which also happened to be Carrick’s first match back in charge. United won 2-0, Mainoo slotted straight back into the rhythm that had won over Erik ten Hag previously, and his form for the rest of the season helped drive United to third place and earn him a World Cup call-up in the first place.
Mainoo’s return to contention has been a running theme of United’s squad build-up this season, and Sunday represents the biggest test yet of whether that trajectory holds.
What happens next
Carrick wants his side playing through the middle, built on close combinations, timing and understanding between the midfield three, and he’ll need exactly that against a City team built to press and pass through the same zones. The Mainoo-Tielemans-Fernandes axis against Anderson, Enzo Fernández and Cherki looks like the contest that decides the derby.
United’s midfield rebuild was designed with exactly this kind of contest in mind, and Mainoo’s job on Sunday is to prove the summer of hurt only sharpened him.
