Abstract: Competitive balance is an important concept for professional team sports and relates with the balance among the sporting capabilities of teams. Among the different approaches introduced in the literature, indices from the industrial organization theory have been used to measure competitive balance. The attention of this study in on the Entropy Index applied in sports in the form of Relative Entropy (R). The application in English Premier League indicates that, in cases with variant number of teams N, R index leads to misleading interpretation of competitive balance. It is shown that the introduced Adjusted Entropy (AH) remains invariant to changes in N and solves the deficiencies of R.
