Manchester City Break U18 Transfer Record with Ayyoub Bouaddi Signing

Manchester City are not easing off the accelerator in the first post-Pep Guardiola summer. If anything, they’ve floored it.

Barely weeks after paying €135 million for Elliot Anderson, City have gone even bigger, confirming the signing of Lille sensation Ayyoub Bouaddi in a deal worth €100m – €95m guaranteed, plus €5m in add-ons. For an 18-year-old. For a teenager who now carries a fee that dwarfs anything previously seen in his age bracket.

Bouaddi, fresh from lighting up the World Cup with Morocco this summer, has signed a five-year contract that runs until 2031. City see him as a cornerstone of their next era, the kind of player you build a midfield around, not just a headline for the window.

In the club’s announcement, Bouaddi didn’t bother to hide the scale of the move for him personally.

“Manchester City are, for me, the best Club in the world. It’s a dream to be here and be able to call myself a City player. I have spent most of my life working hard to become the best player I can be and reach the top of the game,” he said, framing the transfer as the culmination of a journey that has barely begun at senior level.

This comes just days after City sanctioned the departure of 2024 Ballon d'Or winner Rodri, who joined Barcelona in a €76.5m deal including add-ons. One midfield pillar exits, another arrives at a premium. The message is clear: there will be no slow fade from the Guardiola era. The squad is being torn up and rebuilt at full price.

Bouaddi’s current market value sits around €80m, but this is a summer where valuations feel more like suggestions than limits. With fees spiralling, City always knew a nine-figure package would be the number to finally unlock Lille’s resistance. They paid it.

A record not just broken, but obliterated

On the U18 transfer charts, Bouaddi hasn’t nudged the bar. He has launched it into a different stratosphere.

The €100m fee more than doubles the previous record for a player under 18, set when Manchester United paid Lille €62m to sign Leny Yoro in the 2024/25 season. Yoro now drops to second on the all-time list, his landmark deal suddenly looking almost modest.

Behind them, the next names are already familiar. Endrick sits third, Estêvão fourth, both symbols of the Brazilian production line that Europe’s giants now scout years in advance. Real Madrid’s aggressive youth strategy dominates the rest of the upper tier: Franco Mastantuono, Vinicius Junior and Rodrygo all joined Los Blancos at 18 for €45m each, fees that once felt extravagant for teenagers but now read like the going rate for the very best.

Further down, Tottenham’s €41.4m move for Archie Gray from Leeds takes eighth spot, a reminder that English clubs are just as willing to gamble big on domestic prospects. Alessandro Bastoni’s switch to Inter sits in ninth, another example of a club betting heavily on a defender’s long-term ceiling rather than immediate output.

Wolves’ €40m signing of Fábio Silva completes the current top 10, a move that once raised eyebrows for its scale and timing. It now serves as the final marker in a list that has just been dramatically reshaped. Luke Shaw’s €37.5m transfer from Southampton to Manchester United back in 2014, which stood for years as a benchmark for teenage deals, has finally been forced out of the elite bracket after 12 seasons.

Bouaddi’s arrival at City doesn’t just set a new record; it recalibrates what clubs are prepared to pay for potential. The numbers are eye-watering. The expectations will be, too.

Now the question hangs over the Etihad: can an 18-year-old, signed for €100m in the shadow of a Ballon d’Or winner’s departure, carry the weight of a new era?
