COMPETITIVE BALANCE IN FOOTBALL: A COMPARATIVE STUDY BETWEEN BRAZIL AND THE MAIN EUROPEAN LEAGUES (2003-2016)

ABSTRACT The present study compared the competitive balance (CB) of Brazilian professional football with those of Germany, Spain, France, England, Italy and Portugal first division leagues, between the period from 2003/2004 to 2016/2017. In addition, a trend line of the period and the overall effect was analysed. The CB was measured by the concentration of points by the first four teams placed in the final standings (C4ICB). Descriptive values showed that the competitions were not fully balanced (i.e. C4ICB> 100). (Md= 145, 148, 148, 152 and 155, respectively, p<0.05), with no differences for France (Md= 140), compared to Germany, Spain, Italy, England and Portugal (Md= 140, p> 0.05). The CB trend lines for Spain, Portugal and the overall effect were significant and showed a decline in the period (p <0.05). There was more stable behavior for Brazil and Italy, observing tendencies to significant models for the increments in the German and French leagues and a reduction in the CB in the English league. It is concluded that the Brazilian league was the most balanced in this period. Globally, there has been a growing inequality in these leagues, which may implicate in the success and attractiveness of the leagues in the future.
