Lionel Messi put the icing on the cake as Barcelona clinched the La Liga title with a 4-2 victory over Deportivo La Coruna, who were relegated.
Barca went into the match knowing a point would be enough to see them regain the trophy with four matches still to play.
They did not have things all their own way against a spirited Depor, who fought back to level through Lucas Perez and Emre Colak after Philippe Coutinho and Messi had put Barca 2-0 up.
Depor were forced to push forward knowing only victory would be enough to keep their survival hopes alive and they paid the price as Messi added two late goals to complete the 46th hat-trick of his career.
The on-pitch celebrations were muted, perhaps out of respect for their dejected opponents, but Barca, who remain unbeaten in the league, cannot be denied a seventh title in 10 seasons.
