Bayern is winning every year because they have are making good investments when it comes to signing top quality players especially from rival teams like Leverkusen and Dortmund who stands as a threat to bayern let be frank other teams in the bundesliga has not done enough when it comes to strengthening their squad for any title challenge.
Next season, Bayern Munich will likely dominate the title race again, as teams like Leverkusen and Dortmund haven't focused much on recruiting quality players at this point. So, I don't think another team will overwhelm Bayern Munich next season, as they'll be challenging for the Bundesliga title again, although the competition will be fierce. However, that's unlikely to happen for Bayern Munich. They still have enough strength to put up a strong fight against any team in the Bundesliga.
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.
