Manchester City are reportedly close to completing the signing of Lille midfielder Ayyoub Bouaddi, with an agreement on the transfer believed to be in place and only the official announcement remaining.

• Ayyoub Bouaddi’s reported €100m move to Manchester City could make him the most expensive U19 player ever.

• Leny Yoro’s €62m transfer currently ranks as the most expensive completed U19 deal.

• Real Madrid and Premier League clubs dominate the list of the most expensive teenage transfers.

The reported €100 million deal would make the 18-year-old one of the most expensive teenagers in football history and establish a new benchmark for transfer fees paid for elite young players.

According to Transfermarkt figures analysed by SportingPedia, Bouaddi would move to the top of the ranking of the 15 most expensive transfers involving players aged 18 or younger, provided the reported deal is officially completed.

For this ranking, players are classified as U19, meaning those who were 18 at the time of their transfers are included.

If completed, Bouaddi’s €100 million move to Manchester City would put him €38 million ahead of Leny Yoro, whose €62 million transfer from Lille to Manchester United currently tops the list of completed deals.

The potential transfer would also give Lille the two most expensive U19 sales in football history, with Bouaddi and Yoro occupying first and second place.

There is a significant gap between the top two and the rest of the ranking. Endrick is third at €47.5 million, while Estêvão, Franco Mastantuono, Rodrygo and Vinicius Junior have each been valued at €45 million in their respective transfers.
