It’s because their tiny, brainwashed minds cannot grasp the fact the players would want to pay for a club that has won six of the last elevent titles In the best and most watched league in the world. They would rather believe that it’s because of illegal payments to players, of which there is no evidence whatsoever. Literally none.
All it does is serve to underline their lack of critical thinking and ability to consider things objectively. They have wilfully picked a club to support because they are happy to believe everything they are told about it, and cannot accept thst anyone else would make another choice, because to do so would challenge their pitifully flawed belief system.
It’s been said before, but they are basically a cult, with all the absence of reasoned and proportional thinking processes that accompanies that. They are simply incapable of rational reasoning on the subject.
They are to be pitied.
