Barcelona claimed their 24th La Liga title on Week 38 of the season, narrowly beating fierce rivals Real Madrid to the top spot by one point.
Luis Enrique's men secured successive domestic trophies following a 3-0 victory over Granada on Saturday, while Real beat Deportivo La Coruna by two goals to nil at Estadio Riazor.
Cristiano Ronaldo netted twice for Los Blancos before being replaced at half-time as he notched 50 goals in a season for the sixth consecutive year.
However, it proved not to be enough, as Barca clinched a vital three points after Luis Suarez netted a trio of strikes to take his La Liga goal tally to 40 for the campaign.
