Barcelona have won LaLiga for a 29th time after beating Espanyol 2-0 on Thursday night.
The Catalan giants needed just three points from their final three games to regain the Spanish top flight title after they beat Real Madrid 4-3 in an enthralling El Clasico on Sunday.
They faced a trip to city rivals Espanyol, who are languishing in 16th place, and after a goalless first half, a moment of magic from Lamine Yamal put Hansi Flick's side ahead.
After receiving the ball on the right touchline, the 17-year-old cut inside before curling a sublime left-footed effort into the top corner.
Espanyol kept fighting, and put Barcelona under pressure, but their hopes were hampered when Leandro Cabrera was dismissed following a VAR review after he was found to have elbowed Yamal off the ball.
Wojciech Szczesny was forced into a couple of late saves, but the Catalans ultimately held firm before Fermin Lopez added the gloss on the victory with a late second after he was set up by Yamal.
The victory, at the home of their rivals, ensured they would be taking the title back off Real Madrid after a brilliant season.
