It might be premature to completely write off teams like Stuttgart, Leipzig, and Dortmund from the title race. Dortmund have a history of making comebacks. Football seasons are long, and teams can experience fluctuations in form, especially Leverkusen who don't have a good quality depth. Dortmund has the talent and experience to turn things around, especially if they address any issues affecting their consistency.
I dont agree that Leverkusen dont have a good quality.
They for sure have and we can see that on the table where are they now the number 1.
The question is can they keep that good quality over the whole season , in my opinion its possible.
Also i hope that Dortmund maybe can make a comeback to join the race for the title.
