I think you (or your countryman) should think twice before voting one of these managers again, if a manager wants to be re-electected, its his decision, i don't see why he should be banned, if people think he cheated or did things wrong, he won't get votes, very easy.... besides, their performance might be judged after the U-21 World Cup, not before.
Also, i believe you should worry about your team, and should stop requesting unnecessary changes.
