Lol, that is true. In any given year, Bayern "should" be winning the league, they are spending 5 times more than their closest rivals Dortmund. And in theory, Dortmund should be second place every year too, but that doesn't happen, so did Bayern winning because Leverkusen won a year ago.
Bayern Munich remains the most favored club in the Bundesliga next season. Yes, they continue to strive to strengthen their squad by bringing in several top players. As for Dortmund, they are also making similar efforts, but not as significant as Bayern Munich.
So far, their top signings this season are Jobe Bellingham (young central midfielder) and Yan Couto (right-back) from Manchester City. However, the transfer window is still relatively closed, and there have been no further moves.
