Over the years, head coaches, managers, and other persons in charge, have learned that it is not only the physiological, but especially the psychological structure of a sports team that needs to be monitored constantly (Sauer, 2017). One key element underlying the basic psychological structure that support sport clubs is interpersonal relationships. The objective of this study was to examine the nature and extent of interpersonal relationships among coaches, managers and players in Fasil Kenema and Bahir Dar Kenema Football clubs. Considering all the players, coaches and managers in both clubs through available sampling, the study employed questionnaire to collect data from these 58 participants. Using correlational design, the study attempts to determine the degree of interpersonal relationship and its significant predictors. Mean, standard deviation, independent sample t-test and multiple regressions are used to analyze the data. Results indicated that there is high interpersonal relationship among players, coaches and managers within Fasil Kenema and Bahir Dar Football Clubs. There was statistically significant difference in interpersonal relationships in these clubs. Regarding, player-coach, and player-player relationships were found to be significant predictors of team performance. However, coach-manager and player manager relationships were not similar as other variables in significant predictors of team performance. Based on these findings, recommendations were made. Regarding improvement of the relative contribution of each dyad, clubs should be needed to consider or special attention on coach manager and player manager relationship as it does not predict team performance.
