Looks like we are just waiting for Dortmund's efforts this time whether the club will return to be a challenger to Bayern Munich.
Don't expect too much from this team. Dortmund is a business club; they don't focus on trophies but rather on managing their players so they can be sold at a high price.
Leverkusen? Finishing in the top four is already a good thing for them, especially considering Ten Hag career.

Technically correct, but there does need to be a club that can truly compete with Bayern this season because, after all, the Bundesliga will return to being as monotonous as it was in previous seasons, where Bayern always ran away with the title.
At the moment, it's a bit difficult to see which club could do that. Dortmund, as you mentioned, is a business-oriented club that focuses solely on the financial aspects of player transfers, and I'm lowering my expectations for Leverkusen this season due to their coach.
It’s not about underestimating them, but the facts speak for themselves. In a friendly match, they lost by a significant margin, and how he managed Manchester United over the past few seasons. So, I don’t want to raise my expectations for Leverkusen this season.
