I have calculated a score for each of the football teams that play in the 6 major leagues in Europe. The method is explained in the infographic.
In the infographic there are two types of classifications based on this score: the 10 best teams in Europe and the 5 best teams for each country.
Then there are the teams that won at least one competition during the year, and finally the rankings with the best Points per game, Average goals for and Average goals against scores.
