Manchester City have signed Argentina Under-17 midfielder Claudio Echeverri from River Plate.
City will pay about £12.5m for Echeverri, who has signed a four-and-a-half-year contract that runs to 2028.
The 18-year-old, who has made six first-team appearances for River Plate, will remain with the Argentine club throughout 2024.
City agreed a similar deal with River for Argentina forward Julian Alvarez in January 2022.
Echeverri was Argentina's captain at the U17 World Cup in November and scored a hat-trick as they beat Brazil 3-0 in the quarter-finals.
He finished the tournament with five goals as Argentina came fourth after losing the third-place play-off.
