Abstract
This longitudinal study investigates whether young talented football players from a Dutch premier league club rate their own performances differently than their coach. Existing literature about this mismatch suggests that players probably rate themselves higher than their coach. Getting insights into this potential mismatch can allow sports psychologists to develop targeted interventions aimed at improving communication strategies between coaches and players, thus enhancing player development. Performance was measured by using a single item questionnaire for every day the 39 players were at the club, across two seasons. Differences were measured by performing a paired samples t-test. Results show that there is a significant difference between players’ own performance ratings and their coaches’ ratings of their performances with t(749) = -3.306, p < .001, d = -0.121. A possible explanation for the results is that the present research was conducted at the group level, however, previous research suggests that group-level results are not always applicable to individual-level results, which is known as the nonergodicity problem. This study contributes to science by providing an insight into players’ and coaches’ evaluations of performance over a long period. Gaining knowledge about performance mismatches between players and coaches can contribute to player development. Keywords: performance, mismatch, football players, coaches, nonergodicity
