Stuttgart let go of many important players for the team and now I doubt that they will be able to stay at the top of the standings again.
I agree that a lot of very good players was leaving Stuttgart but as far i have seen yesterday on Sky Transfer News Deniz Undav will be stay in Stuttgart.
And his contract will be going to 2027 and i think that is a very good thing for Stuttgart even he wasnt cheap for them.
And considering that Stuttgart will most likely be uncompetitive in the new season,
Dortmund will have three main competitors left, Bayern, Bayer and Leipzig, so yes, they will be in the top 4.
I would not cut Stuttgart off and for sure they will and have to be competitive when they playing in the Champions League and the German League.
Maybe they getting a few young good players in the next weeks , how knows.
