The Blaugrana wrapped up the Spanish championship on Saturday, and an array of the side's stars have taken to social media to express their delight with securing the league
Barca would have tied up the league title regardless of the Blancos' result in Catalunya by beating Atletico Madrid a day later, but their arch-rivals could only muster a 1-1 draw - thus handing FCB the championship without kicking a ball.
Speaking via his profile on the Chinese social networking site Tencent Weibo, the Argentine forward wrote: "After a great year's work I'm happy to celebrate the title! Congratulations to my team-mates!"
Meanwhile, Messi's colleagues Dani Alves and Cesc Fabregas took to Twitter to air their jubilation with Barca's Liga success.
The former Sevilla man posted a picture of coach Tito Vilanova and fellow defender Eric Abidal - both of whom returned to football after successfully battling cancer, and added: "Congratulations to all my colleagues for the championship, especially those in the photo! This is for you Tito and Abi."Fabregas, meanwhile, tweeted: "Today is a great day, the result of a brilliant season! I am really happy I can celebrate my first Liga title! #ForcaBarca #LigaBBVA."
And last but not least, it was a day to remember for Andres Iniesta who also celebrated his 29th birthday, and the midfielder rather fittingly posted a picture of himself with a cake, before writing: "The best gift, turned 29 and won the league... The reward for the work of the whole year!!"
