I also don't know why people underestimate Real Madrid's amazing success last season. It may not be seen as true that their luck helped them also but this wasn't the thing all about them in the end. They deserved to eliminate every single one of their opponents until achieving the title. They eliminated very big teams consecutively too. I don't think that any team can do this very difficult job only thanks to their luck. Real Madrid fought really hard and particularly their offensive performance helped them do this.
