There is no chance of underestimating the Bayern Munich team. Bayern Munich team is favorite in this match considering all statistics. First it's Bayern Munich's home match. At home, Munich's players will surely be very confident. And even against Stuttgart, it will be very difficult to get points against a Bayern Munich team at home in Munich.

Also considering the statistics of the head-to-head matches, the Munich team is the favourite. In the last 15 matches between these two teams, Munich have won 11 matches and lost 2 matches. The remaining two matches were drawn. But an important point is that Bayern Munich lost 3-1 away against Stuttgart last season. However, Munich won the home match 3-0.
Although Munich failed to win in the last two matches, I hope the Munich players will not make any mistakes in the next match. And Bayern Munich will get 3 points against Stuttgart.
There is no doubt that Bayern Munich are the favorites to win this match, they are superior from any point of view, there is nothing that makes Stuttgart superior in this meeting. But that does not mean they can underestimate their opponents this time, because after all it is an advantage on paper that could happen on the field something very different. This is football where everything can happen as a surprise. Bayern Munich will also act as the host which means they will get full support from their supporters. On the other hand Stuttgart does not have brilliant statistics from the 6 matches they have played, but they are not bad either. A draw is the result that will be the target of the away team in my opinion, that is a realistic target for Stuttgart.
Yes and I think we all agree in responding to the Bayern Munich vs Stuttgart match, as you said that there is no advantage for Stuttgart from any side, they will play away and we can see that now they have started the season poorly which makes them now have to be in 8th position in the standings, even though last season they performed quite brilliantly by being able to finish in second place under Leverkusen, but anyway anything is very possible to happen to a team in a different season and also on the other hand I can't use their poor performance in starting the current season as a benchmark to determine their position at the end of the season, because it is still possible for them to return to the top four.
Bayern Munich will play at home and of course this is a match that they will not waste even though in general this should not be a too difficult match for them, but anyway getting three full points is a must for them considering Leipzig who continues to chase them in the standings.
