Barcelona president Josep Maria Bartomeu was pleased with their Copa del Rey final triumph over Sevilla.
Barca won 5-0 at the Metropolitano.
"Winning the double would be historic because we haven't experienced that too many times," Bartomeu explained in an interview post-match.
"Everyone who has watched today's match has enjoyed it, we haven't seen our team play at such a high level for a long time.
"If we win the league it would be an excellent year, we hope to secure the LaLiga title as soon as possible."
