The problem is that, besides Dortmund fans, the entire Bundesliga is suffering - it’s hard to call the league interesting when the champion has not changed for 11 years. But it seems to me that in the coming years everything may change - Bayern is losing its position every year and competition may intensify not due to the fact that everyone else will become stronger, but due to the fact that Bayern will become weaker.
As a big club, Bayern Munchen will always try to increase its strength every season, so that its dominance is not surpassed by other Bundesliga clubs. Looking at last season, Dortmund was almost able to do it, but this season Munchen has more competitive competition than the previous season with the addition of competing clubs such as Laverkusen. I hope the Bundesliga can be won by a club other than Munchen, at least for a season or two, this will make their league less boring.
Munchen performance may decline, but of course other clubs must be more consistent than them. What is clear is that breaking their dominance is very difficult to do, as proven by more than a decade this has not been possible. Dortmund, Laverkusen, VfB and Leipzig must have balanced strength to tackle Munchen this season, because I think these four clubs can do it better than other clubs in the Bundesliga.
