By everybody's logic we must be at an incredible disadvantage because we apparently play in a weak league, in which we don't get tested at all. That would offset the purported advantage of having the league wrapped up that early. Thus, the conclusion you guys draw is flawed.
There is a fine line between having a comfortable lead but still being on your toes and having a comfortable lead while becoming lackadaisical. I believe we're at a disadvantage because in the last three years we had it too easy in the league. For what it's worth it would have been arguably the same for Bayern had they played in any other league besides La Liga.
You can't compare our treble year with our current situation, or that of last year for that matter. The foundation of our treble year was our mentality. After combing back from an awful 2011/12 year, when we bottled the league, the cup and the Champions League in our own backyard, our team was determined and obsessed of rampaging their way to every possible trophy you can win in a season, especially the CL. Last year, we unfortunately lacked that mentality. Mind you no team in the world can maintain that mentality for a long spell anyways.
