Bundesliga top second standings automatically will be for Bayern Leverkusen and Bayern Munich, third and fourth standings seems will be place for VfB Stuttgart and RB Leipzig with both teams left one point only. Have problem for Dortmund can't return with top performance and left 6 points behind Leipzig on the fourth position standings. Dortmund performance in this season not promising yet and out from top fourth standings much problem for them how to get Champion League ticket next although their performance in Champion League most impressive get qualify to next round.
Dortmund have several easily matches after Bundesliga resume on middle January, if can take three points will not close for raising Champion League spot standings but depend on top fourth teams on impressive perform or not.
I still believe Leverkusen can still maintain the top spot on the standing because they are still in an very good form and are yet to show any sign of set back with their form so I definitely don't think they are in any form going to loose the top spot soonest the fear I have for the has to do with the number of goals they have of which Munich is ahead of them by goals.
Stuttgart and Leipzig can actually battle for the third position but then Dortmund is still very likely to get back amongst top four, if only they are able to improve their performance soonest, they aren't a weak side but seem to be having some few challenges in recent times, Stuttgart has been able to maintain a very healthy form recently which has earned them a consistent spot around the top five and I think they can finish amongst top for much more than Leipzig could.
