Intra-team competition occurs among the players, especially since the rewards such as transfer fee and match bonus, which are in the nature of professional football, are high. This competition can be the source of the emergence of bullying behaviors. As a coach, when bullying behavior occurs, I warn the bullying athlete and tell him that it is unethical and unfair. I protect the victim by providing social and psychological support. I create a sense of importance to the player exposed to bullying, establish open communication, and try to increase his motivation by dealing with his problems more closely. In general, I explain the negative aspects of bullying behaviors to all athletes and emphasize that it will have a negative impact on team culture and performance.
