I believe Stuttgart will manage to qualify for the Champions League group stage, what is your opinion? I know there is a good progress in Dortmund and Leipzig's form recently as well but a gap of six points is a really good advantage for Stuttgart to make it. 
I agree with you because Stuttgart has been very impressive at this middle of the season because there record lately is very commendable Whereas there last six matches has been so favourable for them because they were able to win five matches and draw just one match which shows that they are in a good shape and like you said there points difference with Borussia Dortmund and RB Leipzig is quite much because it will take time for Borussia Dortmund to get to the same points with Stuttgart because checking the matches Stuttgart will play they will have an advantage of wining most of the matches, so for now is actually possible that Stuttgart will qualify for the champions League next season.
