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.
You said they are running successfully and that is correct if you take the table as the reference point. The disappoint part is that Bayern's success does not only comprise their performance, but also the performance of their competitors and here Dortmund in specific. If Bayern now loses the last three games and Dortmund does the same, the end result will be a success for Bayern and this is the best approach to describe what happened this season. When you say that Bayern is successful right now, yes they are because Dortmund is not. Usually when we talk about a team being successful, we say that because they win their games and play well. But this is still not what Bayern is doing. They aren't successful, they are lucky.
Dortmund are just waiting for Munich to slip with a draw or defeat so they can't win the league this season, Dortmund seems to be focused on the remaining final matches of the season compared to Munich it seems that Dortmund's opponents are easier than Munich, I think Dortmund always has the possibility to win the league in this season because the difference is only two points with Munich, if Munich loses or draws in the next match then Dortmund are ready to shift them.
Many changes when Munich changed their coach and there is also a lot that needs to be fixed from their squad team as well so that Munich in the next season must pay attention to this and overhaul everything for the better, but besides that Munich is currently only focused on hunting to win the league and sweep net remaining games at the end of the season
