FC Barcelona will not move to another championship. The club's management, I read somewhere on the Internet, received an official response from the president of Spanish football that the team will play in Spain. Barça for me is a Spanish team and no other. I am a fan of the club and continue to be a fan, for tomorrow's match I want to make a small prediction and put 500 rubles on the victory of the Catalans against Malaga.
Barcelona itself has recently announced that it is not going to move anywhere. This is financially inconvenient. Real Madrid alone - Barcelona how much money and popularity it brings.
In theory - why not. If the independence of Catalonia is recognized, Barcelona may try to change the regular season. But in fact, in my opinion, this situation is unlikely: 1) It is extremely unprofitable for UEFA to obtain such a precedent in the form of political interference in football affairs. Such a situation may simply discredit the organization and its leadership. And therefore they may well hinder such a course of events 2) The confrontation between Real and Barcelona is one of the most profitable and promoted in the world. Refusing to regularly host a match between these teams means financial losses both for the club itself and various sponsors. 3) Television rights to show Ligue 1 cost much less than La Liga, and as a result, Barseleona's move to France does not look like a good opportunity for club to increase your income. I will also add that UEFA's legal documents certainly regulate in every possible way the possibility of a club's transition from one championship to another. So maybe someone can find one of them and provide more reliable information about this
