you're right about that. Bundesliga needs some big investors to help the competition become more competitive. It's not so difficult to talk about the competition itself. So many times bayern have been dominating this competition but i hope that if there will be something new in bundesliga.
that will be pretty interesting if there will be some new investors to the small clubs in bundesliga which will make competition become even strict.
Well, there are five reasons why the Bundesliga isn't so competitive.
1. domination of bayern munich.
if there is a party responsible for the supremacy of Bayern Munich itself who is able to answer it. because they have quality players, squad depth, top managers to die hard fans. "The Bavarians have it all"
2. too many young players.
however talented, they are still in the learning stage and still need a lot of experience.
3. inconsistent appearance.
Apart from having the qualities of a champion, Bayern Munich's dominance is also much helped by inconsistent performances by its competitors.
4. Profitable business.
many clubs in the Bundesliga sell important players, Bundesliga clubs are famous for supplying their great young players throughout the European leagues.
5. the 50+1 rule, a rule that requires 51% ownership to be owned by club members. while the remaining 49% shares are the maximum limit for external investors.
I think point 5 can answer from your post. that's why the Bundesliga is difficult to become a more competitive league.
