The Argentina international took to social media to display his delight at winning the Spanish top flight.
As on so many occasions this season, Lionel Messi was the man to fire the Catalan powerhouses to victory, with the Argentine’s second-half strike separating the teams in a tight fixture.
The victory meant the Camp Nou side’s lead over Real Madrid at the top of the pile became unassailable, with Barcelona now turning their focus to finals in the Champions League and Copa del Rey against Juventus and Athletic Bilbao respectively.
Messi, who took his tally to 41 league goals for the season at the Estadio Vicente Calderon, posted a celebratory message on Facebook following the Blaugrana’s La Liga confirmation.
The mercurial forward posted a picture alongside his attacking team-mates Neymar and Luis Suarez, who he has struck up an unbelievable bond with this season in the Barcelona attacking line.
Few would bet against Barcelona completing their treble, with Messi the driving force for his side - especially since the turn of the year.
¡Campeones!!! ¡La Liga es nuestra!!!
