Because people knew that Bayern Munich was going to win the league title, I believe people began to lose interest in the Bundesliga. It seems that suddenly there is a possibility that this is not going to be the case. It is for this reason that I believe people are becoming more interested in the Bundesliga again. Nevertheless, the problem with Bayern Munich is that they have enough money to quickly fix any problems that they may have. I think that this time it is going to be either a change of authority or the addition of Cristiano Ronaldo to the team. My opinion is that either one of these options will be able to solve the problem. Even so, I agree with you that the Bundesliga is once again interesting to watch.
Honestly what comes to my mind is people are interested in the Bundesliga or are they just interested in the performance of Bayern Munich who got a negative result in their 4 matches? Because to be honest I also think a little about the Bundesliga. Changes in position in the standings, at the top of the standings precisely because Bayern Munich is in a negative trend. If they come back then the situation will change soon and I'm sure of that.
It is understandable that people are just tired of watching the same team win the Bundesliga title year after year. I think it has come to a point where people actually would be happy if Bayern Munich did not win the title of the Bundesliga this season. It basically just does not matter to them which team wins the Bundesliga title except for Bayern Munich. I think that's why people are so excited about the fact that they are performing poorly in the Bundesliga this year. Although it is too early to make any predictions, I think Dortmund will have a good chance of winning this season if they can be consistent throughout the whole season.
