I wouldn’t worry too much. What are they going to do - beat up on Espanyol and Real Sociedad all season? Nothing is going to happen either with independence or La Liga but maybe consider transferring your support to one of the little guys - supporting Barca is like supporting the Broncos!
Sociedad are Basque. Girona and Espanyol are the other two Catalonian sides. Let Barca leave the Primera Division, banish Real Madrid (don’t care how they do it,) and let the other clubs fight it out in a proper competitive league. Barcelona y Real pueden chupar mis bolas!
Los Vascos have been chasing independence for ages as well, so much so they blew people up and it achieved nothing. Funny how these things only really flare up when the country is economically in the poo. Once the country bounces back and aren’t reliant on Basque country’s industry & natural resources and Catalonia’s tourism the talks will die down.
The Basque, Galicia and Catalonians all have autonomous recognition in the Spanish constitution, not sure why they need to push it much farther.
