Former Barcelona president Josip Maria Bartomeu was in the stands for their Copa del Rey win at Barbastro.
Barca managed to survive a second-half fight-back by the hosts to win 3-2 against the minnows.
A surprise spectator was Bartoemeu, who has been at odds with the current board and president Joan Laporta.
Bartomeu took photos with fans and was seen smiling and relaxed while the television cameras focused on him. Bartomeu was president of Barcelona between 2014 and 2020.
Current Barca president Joan Laporta missed the tie, with vice-president Rafa Yuste the highest ranking member of the board present for the game.
