Comparativo entre o campeonato brasileiro de futebol e as principais ligas europeias de futebol: uma análise estatística

Abstract

Although football is the most popular sport in Brazil, the brazilian football league is underrepresented in scientific studies that analyse technical and tactical aspects of the sport. Studies that compare leagues are relatively common, mas they usually focus on the major european leagues. This work aims to analyse how the brazilian football league compares, in technical and tactical aspects, to the four major european football leagues: English Premier League, Spanish La Liga, German Bundesliga and Italian Serie A. Even though there is a big difference in revenue and market value of the squads, this work explores the opportunity to analyse if these differences translate into big differences concerning technical and tactical aspects of the sport, by analysing a few notational performance metrics. Besides this, this work also analyses the internal balance of the leagues. For the analyses, we collected five seasons of leagues’ and squads’ notational data. Results showed that the brazilian league has worse indicators in many performance metrics, especially when considering only the top clubs from ranking tables in each season. However, it was also possible to observe that some metrics were similar ou even better, despite the economic discrepancy. It was also possible to see that the brazilian league if more balanced than the major european leagues.
