United States youth international Konrad de la Fuente has signed a new contract with Barcelona, committing his future to the Spanish champions until 2022.
De la Fuente's new terms include a €50 million release clause which will rise to €100m if he is promoted to the first-team before the expiration of the deal.
He will form part of the club's B team next season, who are playing in the third tier of Spanish football but could be promoted to the second division later this summer.
They are preparing for the playoffs which take place in July across several locations in the south of Spain. De la Fuente, who started the season with the under-19s, is already part of the squad.
Barca had to work hard to convince the young winger to stay at Camp Nou after a number of clubs showed an interest in him with his contract set to expire this summer.
De la Fuente, 18, looked set to move to German side Hertha Berlin in December, but Barca managed to persuade him that he would get chances to progress at the Catalan club.
The Miami-native moved to Barcelona with his parents when he was 10 and was incorporated into Barca's La Masia academy in 2014.
