No one doubts that Bayern Munich will once again dominate the Bundesliga and in the previous 2 seasons only Leverkusen made a surprise and broke Bayern Munich's dominance but now we don't see any other Bundesliga team building a team that can rival Bayern Munich.
Bayern now only need to focus on European competitions and that's what they've always done, they've put the Bundesliga aside a bit and still won the title.
When you are this much richer than anyone close to you, it is obvious that you are going to win the league. Sure they had just one season where they failed, which was an uncanny result from Leverkusen who just refused to lose to anyone, but aside from that one odd season, they won all the titles. For the past 12-13 years, they won all titles but one if I am not wrong.
The only way for anyone else to ever have a chance, would be getting a rich owner who can spend as much as Bayern, but not that many people could spend 300+ million a year on a team, so I am pretty sure that Bayern is comfortable at the moment and won't face that much difficulty from any other team. It does make the league a bit boring, but it is the reality we have to learn to accept.
