Barcelona attacker Ansu Fati has agreed a new six-year deal and become the second player from the club to have his buy-out clause set at 1 billion euros ($A1.55b).
The Bissau-born teenager had been linked with a move elsewhere but has committed his future to the financially-stricken Catalan giants.
The Spain international's previous contract ran until the end of this season, but Barca had the option to extend that by a further two years.
Fati's new contract will officially be signed on Thursday.
The news comes a week after fellow Spanish teen Pedri signed a five-year extension at Camp Nou which included a 1 billion euros ($A1.55b) release clause.
In 47 appearances for Barca, Fati has scored 15 goals and is the second youngest player to debut for them after he made his first appearance aged 16 and 298 days.
The 18-year-old has racked up numerous records during the past three seasons, becoming Barcelona's youngest La Liga goalscorer, the youngest player to score and assist in a league match and the club's youngest player in the Champions League.
After suffering a torn meniscus in his left knee in November, Fati returned after 10 months on the sidelines to help lift some of the gloom at the Nou Camp with two goals in five appearances this season.
A product of Barca's La Masia academy, he took on the No.10 shirt after Lionel Messi's departure for Paris Saint-Germain in the summer.
The news was announced soon after Fati had appeared as a half-time substitute in Barcelona's 1-0 win over Dynamo Kiev in the Champions League on Wednesday.
