Bayern Munich’s aim is to achieve the next coming season’s title; that’s why we can see their main focus is to keep good players in their teams, but that doesn’t mean they will be able to repeat the same thing next coming. Because I can see almost every team also busy signing players for next season, and that’s what will make the season so competitive.
In fact, most clubs in the Bundesliga always aim for the title every season.
However, Bayern Munich already has many advantages in terms of players, coaches, and a fairly strong financial base.
That's why Bayern Munich always aims for the title every season. Despite losing key players, they are always able to recruit new players with better talent, even if those players are very expensive.
In my opinion, after Bayer Leverkusen lost their best player this season and got a new coach with a poor reputation, I don't think the Bundesliga will be competitive next season.
