Barcelona's teenagers were crowned European champions by beating Chelsea 3-0 in the UEFA Youth League final on Monday.
The teams have combined to win four titles in the competition's five-year history, though Barcelona outclassed Chelsea to regain the trophy it last won in 2014.
Barcelona's 17-year-old Venezuelan forward Alejandro Marques scored in each half, and Abel Ruiz added a third in stoppage time.
Chelsea twice hit the frame of the Spanish side's goal in the second half when trailing by two goals.
The English club won back-to-back UEFA youth titles in 2015 and 2016. Salzburg won the other title last year.
