The only way for anyone else to ever have a chance, would be getting a rich owner who can spend as much as Bayern, but not that many people could spend 300+ million a year on a team, so I am pretty sure that Bayern is comfortable at the moment and won't face that much difficulty from any other team. It does make the league a bit boring, but it is the reality we have to learn to accept.
Whatever the situations but the fact is only this we enjoyed or really enjoyable are these leagues or titles which are based on the competition, where their results are unpredictable . Bayern Munich is a strong team and everyone behind the camera knows that it is difficult to defeat them or their success is confirmed even before any competition. I think the other clubs need to be that strong for a healthy Bayern Munich squad is strong and they spent a lot of money to maintain their strongest side. Other clubs are also in the race to win the Bundesliga title but i think by doing some Amendments a tough time could be given to the strong team and after a healthy competition results could be different. Which definitely gives the new angel of thought to every viewer about the Bundesliga.
