Nico O’Reilly is the kind of late-breaking World Cup story that makes England’s squad feel more interesting than it did a year ago. He is not just a young Manchester City academy player getting a ceremonial look. At 21 years old, he leapt to prominence for Man City this season, not only forcing his way into a regular starting role, but becoming a critical piece in their title push. Suddenly, O’Reilly looks like he could solve one of England’s more awkward roster questions.

O’Reilly’s rise has been fast enough that it almost feels fake. Manchester City announced in September that he had signed a new five-year contract through 2030, and Transfermarkt now values him at $58.8m. That is a huge number for a player who only turned 21 in March, but it reflects how quickly he has gone from academy prospect to real first-team option.

His positional versatility is part of the intrigue. England Football lists him as a defender, but O’Reilly came through City as a midfielder, can operate centrally, and has even played some time in a number ten role. He has spent most of his senior breakthrough playing at left back and has nominally lined up there mostly for City, though often drifting inside to fill more of a midfield role.

England coach Thomas Tuchel has an absurd amount of attacking talent to choose from, but tournament teams are often shaped by the positions where they are not quite as clean. Left back has been one of those spots for England, and O’Reilly gives them a very modern answer: size, technical quality, midfield instincts.

O’Reilly will likely fill the starting left back spot in the World Cup, though that may mean getting up and down the left wing at times, while moving more centrally and underlapping in the channels at others. His role from left back may largely depend on the rest of the England setup, especially who gets deployed in the left wing role in front of him.

That is what makes him more than just a fun young name. O’Reilly could change the shape of the team. If he starts at left back, England can build with him tucked inside, giving Declan Rice and Jude Bellingham another passing option while still keeping enough athleticism behind the ball. If he comes off the bench, he can cover multiple roles without forcing Tuchel to burn extra roster spots on specialists. He has been especially valuable for City crashing the box and using his size to get on the end of crosses, so Tuchel may find ways to get him in position to help in attack.

There is still some risk here. O’Reilly is young, inexperienced internationally, coming off a grueling title chase — and a World Cup knockout game is very different from looking smooth in a Guardiola system. But that is also why he belongs this high on the list. England have plenty of stars everyone already knows. O’Reilly is the player who could go from “interesting squad inclusion” to “wait, England may have found something here” over the course of a month.
