Catalonia intends to press ahead with a referendum on independence on Sunday, despite strong opposition from the Spanish government.

La Liga president Javier Tebas, meanwhile, has attempted to apply pressure on Catalonia by saying the region's top-flight football clubs -- Barca, Espanyol and Girona -- would not be able to continue in the Spanish league in the case of independence.

Catalonia's minister of sport, Gerard Figueras, told La Gazzetta dello Sport: "The great unknown these days is what will happen to professional clubs, where Catalan clubs and in particular Barca will play, seeing that the whole world is obsessed by the issue."

Barca believe they would be able to continue in the Primera Division, regardless of how the push for independence ends.

Along with Real Madrid, they are responsible for a large amount of money the league makes and cutting that source of income off may not be advisable to Tebas.

"Tebas' opinion will not be the only one which really matters," Figueras added. "He will have to consult with the rest of the clubs in the Liga and above all keep in mind the contractual and economic considerations, which are relevant."

Barca continuing to play in the Spanish league would not be in breach of any rules, given there are currently Andorran clubs already represented in the Spanish football pyramid.

Meanwhile, Monaco play in the French league and there are Welsh teams competing in English football.
