At first, I was sure of Union Berlin because they showed impressive performance and managed to be at the top of the standings for a few moments, but over time they played worse and worse until finally, they are currently in 5th place with 8 wins, 3 draws, and 4 losses. looks like this season will belong to Bayern again.
When Bayern Munich plays badly and often loses it's like on purpose because maybe they want to start with a less tough opponent and use a strategy like this to look for winning points in the next game until they finally win first place again. It's very easy for Bayern Munich took first place so they tried to give other teams a chance to get first place and take it again.
Bayern Munich is the richest and most powerful team in the Bundesliga. They spend a lot of money to form squads. The squad has a lot of talented and star players. On the other hand, the other teams in the Bundesliga are not interested in spending a lot of money. And this is why we see Bayern Munich's dominance in the Bundesliga every season. In addition, teams like Dortmund or Union Berlin have not been able to fight for the title due to a lack of consistency in the Bundesliga. Compared to Munich, they are far behind.
