Barcelona won its second straight Spanish league title after defeating Granada 3-0 on Saturday with a hat trick by Luis Suarez in the final round.
The result capped a five-game winning streak that allowed the Catalan club to finish one point ahead of Real Madrid, which fell short despite winning its last 12 league games.
Madrid defeated Deportivo 2-0 in La Coruna with two goals by Cristiano Ronaldo, but it needed Barcelona to stumble in order to clinch its first title since 2012.
After the final whistle in Granada, Barcelona players formed a circle near the benches and jumped up and down while chanting "Campeones, Campeones."
Several hundred fans from both teams invaded the pitch as players struggled to find their way off the pitch.
Barcelona, which finished with 91 points, has won six of the last eight Spanish league titles, and eight of the last 12. It has 24 trophies in total, eight less than Real Madrid, the league's most successful club.
Saturday's win helped Barcelona avoid what would have been a disastrous title loss after it led Madrid by 12 points with nine rounds to go.
