Coaches in sports teams are the most influential people on the team, whose leadership style and behavior determine the performance of the athletes. According to a theoretical and practical standpoint, it is important to examine the kind of coach’s behavior and relationships, and solidarity with other members of the team, which is team cohesion (
1). Between a variety of theories and models related to leadership and teamwork, we used the transformational/transactional axis explained by Burns and improved by Bass and the leader-member exchange (LMX) theory by Graen and UhlBien as cited by Chen; a relationship-based approach to leadership that focuses on the two-way (dyadic) relationship between leaders and followers (
2). The transactional/transformational leadership model relies on the assumption that all leadership styles can be classified into two different models. According to Yukl as cited by Chen, transformational leadership is “the process of influencing major changes in the attitudes and assumptions of organization members (organizational culture) and building commitment for major changes in the organization’s objectives and strategies” (
2). The LMX theory evaluates relationships instead of individual leaders and followers and examines the connections between individuals rather than simply the individuals themselves (
2). The leadership model in exercise is a groundwork for examining the effective processes, the recognition of which can influence the actions and responses of athletes. The central process of the leadership model shows that the behavior of a coach is clearly reflected by the behavior and attitude of his athletes. This model considers the athletes and their behavior as an indicator of their coach’s behavior. One of the most important aspects of deciding on coaches is choosing the coaching style, which determines how to decide what skills and strategies to teach, how to organize the practice and competitions, etc. (
3). Personality characteristics of leaders have frequently been interesting in psychological research. This interest has been mainly in business, educational, and even sports psychology. The phrase “what makes a person special?” might be one of the most frequently asked questions in this area of research and even in everyday life. Because of this, the focus has changed to observing leaders’ behaviors and situational factors. Leadership is one of the most important issues in organizational psychology; hence, it has been extensively researched. This extensive information has built the basics for more specific investigations in other fields, such as sports or educational psychology. Thus, before delving further into the state-of-the-art research in athlete leadership, we are supposed to examine the underlying basics of the issue to set up a common understanding of the leadership concept in general and in sports in particular. Fiedler discriminates between task-oriented and relation-oriented leadership styles, which are more or less effectively determined by the favorableness of a situation. Favorableness is thus controlled by the position power, the task structure, and the relationship between leader and follower. Recent studies have reported similar preference patterns of female and male athletes respecting task and relationship-oriented behaviors. This seems to account for expectations regarding coaches’ and athletes’ leadership behavior. Based on a model of Fiedler’s as cited by Wachsmuth, the leader is expected to be a coordinator of his/her subordinates (
4). To cultivate and grow athletes’ potential in sports, a functional working alliance between the coach and athletes is crucial. An important aspect of the coach-athlete relationship is to enhance performance and success in competitions. Therefore, coaches need to reflect upon their own behavior and understand the motive behind the behavior of others. A good coach must be able to see each athlete as a unique individual and attempt to establish a good rapport with them. Most people do not seem to have a clear picture of their abilities and competencies. The reason for this is that they tend not to know themselves sufficiently. It looks reasonable to propose the idea that individuals tend to perform better provided that they know themselves well, acquire further skills, and enjoy the necessary motivation to do various tasks. In sports, it is very important to know who we are and what we can do. If an athlete is further aware of his or her abilities and potential, one may find success with a much greater chance. Furthermore, understanding the personality traits of athletes can be helpful in accomplishing greater achievements in their range of sports activities. Numerous research studies have been done to demonstrate the effect of personality on sports preferences and the performance of athletes. Hence, the popularity of this area of research has blossomed since the introduction of sports psychology as an academic discipline. In line with that, it is right to say that personality does play an important role in sports and exercise. It could be seen by the extensive research conducted by researchers and practitioners within the sports psychology area. In general, personality could be perceived as the characteristic that makes a person unique. These personal characteristics could determine the consistent and enduring responses of a different individual under different situations (
5). Predicting the likelihood of success of a talented young athlete into a skillful adult athlete has been a dream of every practitioner in sports or any other job. Findings have shown that a wide range of personality traits have been related to the levels of achievement in many sports, including basketball, hockey, and football (
6). All the football team stakeholders and fans expect the best possible results at the commencement of the season. If the team obtains the achievements, people may feel fulfilled and willing for the new season to start. Nevertheless, data showed that not all fans see their expectations fulfilled, and only one team can be the winner in every competition. Consequently, it looks rational that most of the fans will be more dissatisfied at the end of the season. However, probably most of the fans do not think this way, and they will not leave their losing teams. Thus, most of the teams would keep their fans. Previous studies have examined sports performance through different approaches. Some studies have analyzed the competence of players, while others have evaluated the competence of trainers in order to examine the characteristics of the team. Furthermore, a few studies focus on team performance concerning the relative attacking or defensive attitude of the players. Barros and Leach and Barros and García-del-Barrio as cited by González-Gómez and Picazo-Tadeo, examine financial and sporting purposes in order to measure team performance (

For example, personality type one tends to have the following characteristics: Conformist, diligent, detail-oriented, cautious, dutiful, serious, perfectionist, value-oriented, purposeful, and innovative in setting standards for achieving their goals. Type two people have a number of qualities. They are altruistic, generous, empathetic, diligent, and motivated. They have a strong drive to connect with the world. Individuals with type five personalities are usually shy, clever, thoughtful, solitary, innovative, knowledge-oriented, etc. People with type seven tend to be indulgent, joy-seeking, ambitious, inquisitive, restless, entrepreneurial, motivational, etc. To succeed, a person must have different personality traits and skills. Even if all the individual circumstances and factors are favorable, success will not be achieved unless the environmental factors are desirable. In addition to these factors, random factors also play an important role.
