Barcelona squad have a paper fight & sing “Campeones!” on plane to Atletico Madrid

New La Liga champions Barcelona flew to Madrid this morning, in time for their match at Atletico Madrid this evening.

Real Madrid’s 1-1 draw with Espanyol on Saturday night, ensured Barcelona are already La Liga champions for 2012/2013 and judging by their flight to the Spanish capital, they are already in party mood.

The video below has already started to go viral in the Catalan press and judging by the amount of mobile phones in shot, we may well see more versions.

El Mundo Deportivo say Dani Alves was responsible for starting the “paper war” whilst Xavi can clearly be seen taking a few shots at his team mates.

Will Barcelona play with freedom at Atletico and turn it on?

Or is it worth having a bet on Diego Simeone’s side to down Barca while they celebrate?!
