Factors Determining the Market Value of Football Players on the Example of Ekstraklasa

Summary/Abstract: The aim of the study is to answer the question of what factors determine the market value of players and what is their impact on the market valuation of players in Ekstraklasa clubs. Using linear regression, the parameters of the models determining the impact of individual exogenous variables on the market value of footballers in Ekstraklasa clubs were determined. The results of the analysis indicate a significant, positive relationship between the market value of players and the results of clubs in national and international competitions. The expenses on transfers of Ekstraklasa clubs turned out to be negatively correlated with the market valuation of players. Moreover, expenses on salaries and revenues turned out to be positively correlated with the market value of the players in Ekstraklasa clubs. An important factor that has a significant impact on the value of players is also their age. The most valuable players are players with experience at the highest level of competition, who at the same time have many years of professional football career ahead of them. In order to correctly assess the market value of footballers, many factors that could potentially affect their valuation should be taken into account. The business model used by Ekstraklasa clubs is significantly different from those of the leading European leagues, especially those belonging to the top league. The most effective way to find a player with high market value is to invest in the development of young, talented Polish players with high sales potential. The article is an extension of the research on the factors determining the market value of footballers, taking into account many variables that have not been fully verified so far. The study also distinguishes the time span, covering 15 seasons of the Ekstraklasa. A comprehensive approach allows for identifying the main trends in shaping the Polish football market.
