Kobbie Mainoo: from World Cup outcast to Manchester United's key man in the derby

Kobbie Mainoo finished the World Cup without playing a single minute. England reached the semi-finals and lost to Argentina, but the midfielder watched everything from the bench or the stands. Months later, that wound has turned into fuel: the 21-year-old arrives at the Manchester derby as one of Michael Carrick's most important players.

• Mainoo did not play a single minute for England at the World Cup and missed the third-place playoff entirely.
• Thomas Tuchel preferred Elliot Anderson and Declan Rice in the deeper midfield roles.
• Manchester United reshaped their midfield with a £155m outlay and Mainoo has still reclaimed his place.
• In his last three games he has completed 201 of 211 passes and produced 15 defensive contributions in the two league matches.
• He will be central to Sunday's derby against Manchester City at Old Trafford.

A summer of frustration with England

Throughout England's World Cup campaign, reporters became used to seeing Mainoo leave the dressing room first. He walked through the mixed zone staring straight ahead, face blank, as if he could not get away from the stadium quickly enough. The deeper England went in the tournament, the more noticeable the gap between his departure and that of the next player became.

That coldness, even in the heat of competition, is part of a temperament that rarely cracks. Behind the mask, however, there was considerable frustration: Thomas Tuchel continued to leave him out. It was not a one-off decision. The manager used Elliot Anderson and Declan Rice as his holding pair and also handed minutes to Reece James, Jude Bellingham, Jordan Henderson, Morgan Rogers and Nico O'Reilly ahead of Mainoo.

The midfielder did not appear in the semi-final against Argentina and was not even on the bench for the third-place match against France. The Football Association said before that game he had picked up an unspecified injury. For Mainoo it was a lost summer on the pitch, yet still draining physically and mentally because of the training, the travel and the demand to stay focused while waiting.

Returning to Manchester United and the midfield battle

Like every international who reached the final weekend of the World Cup, Mainoo reported late for pre-season. He played the last half hour of the friendly against Milan and little more. On the opening day of the league season he was only fit enough to be a substitute at Hull City, coming on with 23 minutes to go as United trailed 2-0 on their way to a damaging defeat.

The club had rebuilt its midfield at a cost of £155m. Youri Tielemans, Andrey Santos and Carlos Baleba arrived to raise the level, and although Baleba has not yet played because of injury, there was a fair question about where Mainoo would fit. The answer has been emphatic: the academy product has won back his status on merit.

He has been outstanding in every United match since the opening day, against Ipswich, Everton and Sabah.

The numbers behind his starting role in the derby

United supporters have adapted the lyrics of a Billy Ocean song to declare that their team cannot play without Mainoo. The data backs up the chant. In the last three matches he has attempted 211 passes and completed 201, an extraordinary level of security on the ball, especially given how often he receives it and the risk involved in so much of what he does.

• 201 of 211 passes completed across his last three appearances.
• 15 defensive contributions against Ipswich and Everton, the highest in his team.
• An undisputed starter since the opening day, with a standout Champions League display.
• His quick feet and hip-shaking feints keep opponents off balance and open new attacking angles.

Beyond possession, Mainoo is also improving without the ball. His defensive reading has grown and his ability to keep rivals guessing while recalibrating United's attacking lines has become a regular weapon. The big question for Michael Carrick in the derby is who to field alongside him in front of the back four.

The derby against Manchester City: a midfield showdown

Carrick is expected to start Tielemans next to Mainoo, with Bruno Fernandes as the third midfielder. Opposite them will be Elliot Anderson, Enzo Fernández and Rayan Cherki. It is a clash of styles and young talent, and it will probably be decided in that area. If United can impose their inside circulation, the derby will tilt their way.

The duel between Mainoo and Anderson carries an extra edge. Anderson joined City in July after a £116m move from Nottingham Forest, once the Manchester club blew United away with an offer they could not match. On the day of his unveiling, Anderson called City 'the kings of Manchester'. Mainoo will have the chance to answer on the pitch.

The January precedent and Carrick's plan

The last derby at Old Trafford, in January, ended 2-0 to United and was the first game of Carrick's second spell in charge. That day Mainoo immediately returned to the groove that had already won over Erik ten Hag, Ruben Amorim's predecessor. The team produced fast one-touch football and precise triangles, including a memorable sequence in which Matheus Cunha, Luke Shaw and Bruno Fernandes bypassed Rayan Cherki.

That is the style Carrick wants to keep building. Following the arrival of Tielemans and the return of Mason Mount from injury, the manager insists on playing through the middle, with the ball to feet and careful attention to timing and distances. 'It was nice to get Mason on in the second half and see the same things with Andrey Santos. It's the combinations and connections. We have the technical ability to take the ball in central areas and a lot of it depends on understanding where each player wants it,' Carrick said. The evolution is clear: 'It's probably something we have done more of this season.'
