It is obvious that Bayern Munich dominates in a number of areas including reputation financial resources and infrastructure. The Bundesliga championship however measures actual strength on the pitch which goes beyond having a roster full of illustrious players. Numerous variables must come together for a team to be the strongest over the course of the full season not just for a single game or month. The game mental component and any potential complacency that results from ongoing success can have a big impact. It is usual for a team used to winning to mistakenly let its guard down giving hungry and tenacious teams a chance. Such events occurred during this Bundesliga season but ultimately everyone saw the expected conclusion.
I do not think that it does, I think it goes directly into having a good roster on the field and that means if you do a good job as management then you are going to win more often than not, which is proven by the league winners so far in the last decade. Bayern manages their financial situation incredibly well, not only they make a lot of good money, but they also spend that money very wisely and they invest and they earn and they reinvest and so forth.
When you combine all that together that makes it easier for them to spend money on buying players and when they do buy players at a good level then that makes it easier for them to win. Who can afford to put a championship team on the field, wolfsburg or Bayern? It's so simple, be financially strong and get good players and win the title.
