Einfluss des Schiedsrichters auf das informelle Fair play

In sports games fair play is of central importance, because without it the game loses its playful features and the sport loses its original idea. In today's sports world, it can be observed more and more often that the idea of fair play is pushed into the background. Now the question arises what the reasons are for the "disappearance" of fair play. On closer examination it can be established that fair play exists in a modified form. Fair play can be defined in different ways: Formal fair play means adhering to the written rules, whereas informal fair play is directed at the inner attitude of the players. Today, these seem to be oriented primarily towards formal fair play. They describe their behaviour as fair as soon as the referee does not classify it as contrary to the rules. The question therefore arises as to how it.
