The Bundesliga is obviously a lot more interesting this season. There is no longer a huge difference between Bayern Munich and its closest rivals in terms of points. The Bayern Munich team is currently ranked 5th in the table and despite the fact that only seven matches have been played so far, I am genuinely starting to believe that the Bundesliga will likely be decided by a different team this time around.
There is no guarantee that Union Berlin will win the Bundesliga, but I think as long as Bayern Munich is not going to be the league winner, the competition is going to be interesting in this league in the future.
I don't understand how you can call Union Berlin
(a team with the lowest budgets of all Bundesliga teams) a serious competitor of FC Bayern. Union will never ever win the Bundesliga this season, I promise you that. If FC Bayern can be stopped, then only by Borussia Dortmund or RB Leipzig. And so far, it looks like only Dortmund is a serious competitor. RB Leipzig has sadly enough problems of its own.
Despite Bayern playing its weakest season in years, none of the Bundesliga "top teams" can put themselves in a promising position. That's worrying and makes me doubt whether any other team than Bayern should really succeed in winning the Bundesliga at the end of the season. But we will see, miracles happen from time to time.
