Regardless of what Stuttgart are going through, they are quite impressive not only because they won but were able to score a lot of goals, in two matches they managed to score 5 goals each, 3 goals against Mainz and their striker Sehrou Guirassy has scored at least 8 goals, much more than Harry Kane has scored this season, but agree that Stuttgart will start to experience difficulties when facing strong teams and will slowly fall in ranking, but this season they will not repeat the difficulties of last season when they were almost relegated. All teams that experienced difficulties last season certainly wanted to experience what Stuttgart is currently experiencing but were unable to improve their performance because they had players who could be said to be not as good as other teams, and minimal financial support makes it even more difficult.
I like how they started so well this season and are currently top four in the table it shows how serious they're and i believe it would help them this season if they continue with this good form they won't even go close to the relegation zone, so far they won three games out of four with one lose same points with Leipzig who're in the 3rd position, but the difference between them and Leipzig is that they're not really very strong contenders and might begin to decline with time.
There next match is against Darmstadt who're in the relegation zone and expect them to win with a good scoreline like they normally do, because they're more in form and in a more better position in the league table which makes them to be the favorites in the match,well for the past 5 matches both teams have scored eachother ones and drew thrice making me to wonder if the might would end with a draw but i have a feeling that Stuttgart would win based on their current form.
