Europe top leagues champions stats review

Europe top Leagues champions positions by scoring, conceding and balance (GS/GC) in the leagues in which they play

GS: goals scored, GC: goals conceded, GS/g & GC/g: per game ratios

In order to win a league championship, you must have excellent defense and good attack. If you look at the list above, you will notice the importance of defense, however what really maters at the end of the day is to have the best balance between defense and attack (GS/GC). Best example for that point are Bayern, Lille and AthM. Bayern is the fifth best defense in the Bundesliga however  they balanced that with a formidable attacking force. Lille and AthM do not have the best attack in their leagues, however they balanced that with the strength of their defense.
