Will Bayern lose points? I don't think they will lose. They are currently running very successfully. There is no difference between winning a championship by 1 point and winning by 10 points. Right now Dortmund is right behind them, but Bayern Munich is a strong team to win any game they play without stress.
Bayern Munich's next match will be with the Schalke team which is currently in a bad position, so I would assume that Schalke is a very easy opponent for Bayern Munich because in the near future Bayern Munich will play at home to face a team that is not so strong. And Schalke has the potential to experience a drop in ranking if Schalke loses at home to Bayern Munich in the near future, because Bayern Munich is really aiming for victory in the race for the Bundesliga trophy this season.
Schalke is not an opponent who must be too pay attention to and consider, even though they get a victory in the last two matches in the Bundesliga, I don't think they have much motivation to defeat Bayer Munich in the next match, on paper seen from the team of the team, of course Schalke will definitely lose , because indirectly Bayer Munich also had to maintain his position in the top 1 Bundes League to come out to become champions again this season.
The point difference between Bayern Munich and Dortmund is just 1 and this doesn’t mean Dortmund will take Bayern Munich position. Bayern Munich is an experience team in winning Bundesliga and I don't think right now Dortmund can go with championship. Bayern Munich is in their worst state of performance but won't miss opportunity of winning Bundesliga after losing champions league, Bundesliga is very important for them to win.
Even though Bayern Munich has a long history of dominance in the Bundesliga it is crucial to keep in mind that every season is unique. Dortmund is a force to be reckoned with this season as evidenced by the fact that they are presently only one point behind Bayern. Bayern has been having trouble lately but that does not mean they can not get things back on track. Dortmund could however, build on their recent success and triumph if they continue in that direction. In sports anything can happen at the end of the day, thus it is hard to forecast the result with certainty. It will be interesting to see how the rest of the season develops and which club wins the title.
Yes you are right anything can happen in the field, but if you pay attention to how many more will be passed in this Bundesliga, maybe you will have a tendency to think of one team, look at who will be faced by Bayer Munich in the rest of the laga besides Schalke and see too. Who is the opponent in the rest of the Dortmund match in the Bundesliga.
