Abstract:
The purpose of the present study was to statistically investigate the profile of coach replacement in the Greek professional soccer League. A total of 162 coach substitutes for the three major leagues (145 teams) during the 2000-01, 2001-02 and 2002-03 championships were recorded and analyzed. The data comprised of variables related to the frequency of substitute, the performance of the coach on equal number of games and the ranking position of the team. Non-parametric and multivariate statistics were used. The results demonstrated that 70.34% of the soccer teams replace their coach during the three researched championship seasons and the frequency of replacement is significantly increased in the lower divisions (p<0.05). An overall significant increase in ranking position of the team was found for the four consecutive games after coach replacement (p<0.001), on the contrary the comparison between the performance of these teams on the rest of the games before and after the replacement fluctuated at the same levels without significant differences. The ranking position was improved in only 41.4% of the teams after the replacement. Overall, the study confirmed short term positive influence of coach replacement on the team ranking position, while no evidence is provided in support of any middle or long term influence.
