It's not without precedence.
We were the club hardest hit with the European ban.
We had the first of only 2 players banned for diving even after the commission said that there was contact on Niasse.
We were the victims of a fixed champions league draw, the fact that Moyes said publicly that he believed that the draw was fixed and wasn't himself punished for saying that, as a punishment for Moyes would have led to an investigation.
Then the game itself V Viallareal was obviously fixed.
Then they changed the rules on champions league qualification.
Can't really blame people for thinking the worst.
