you are apsolutely right. My favourite league is English PL, it has more great rivalries etc. But Spanish Primera took it over some 3 seasons ago. Just check out the list of final 4 teams in Champions league and Europa league in this period and youll see: Real, Barca, ATM, Bilbao, Sevilla, Valencia. They really took it over.
Regarding Italian Calcio, what happened was Calciopolli, they were dominating Europe in a period before it and than it all colapsed, Juve got relegated, Milan lost money, only Inter remained. Its a shame.
