Phil Foden has signed a new long-term contract with Manchester City, a source familiar with the negotiations told ESPN FC.
The 18-year-old midfielder is highly regarded by City boss Pep Guardiola and is set to receive a significant pay rise in the new deal, although the actual terms are unknown.
Borussia Dortmund and Juventus were reportedly monitoring Foden's situation as he entered the final 18 months of his current contract.
But he has now killed off any hope the European giants had of signing him by putting pen to paper on a new long-term deal at the Etihad Stadium.
Foden has been with City since the age of five and is also a lifelong fan and made his first derby appearance in Sunday's 3-1 victory over Manchester United.
He has made 10 appearances this season and scored his first goal for the club in the Carabao Cup victory over Oxford United in September.
City have also agreed contract extensions with Raheem Sterling, Kevin De Bruyne, Gabriel Jesus, Ederson, David Silva and Sergio Aguero in the past 12 months.
Sources have told ESPN FC they are also keen to tie down John Stones and Leroy Sane to new deals.
