When I first saw the news that Real Madrid wants to leave the Spanish league and join another league because poor referee decisions in most of their matches, I knew that was all done in order to draw the attention of FIFA and other regulatory bodies to look into the matter for them. All clubs in one way or the other face issues like this and they’re still playing actively in their respective leagues. This too shall pass, they just want a faster response to their complains.
It is not easy to leave the league and join another league for team like Real Madrid. Leaving to another league would require approval from UEFA and I believe they will not approve it for many reasons. Besides Real Madrid is one of the founding members and they can complain about poor referee decisions. Such controversial decisions are not only harmful for big club, but also for every club. We generally talk about it when it happens with big clubs. This matter should be considered seriously to maintain fair play in every game.
I agree, eventually it can come down to rule changes if infractions and the rule itself becomes absurd to some degree, so it's nothing that they are often unhappy with the decisions. I don't understand the aggression of many towards them, it would be one thing if they complained and lost, but no, they win and say the officiating is sometimes bad. It's not the same thing
