The Athletic Club squad were in an excellent mood after reaching the final of the Copa del Rey on Thursday night, advancing on away goals after drawing 2-2 on aggregate against Granada, and they celebrated in a peculiar manner.
Striker Asier Villalibre began to play the trumpet in the visitors' dressing room at the Estadio Nuevo Los Carmenes while the rest of the players sang a traditional Athletic chant.
"lalalalala Athletic Club," was sung by the squad.
