That applies not only to the championship but also to relegation. Every team up to place 13 can still be relegated or finish in the relegation zone. The ship has almost sailed for Hertha Berlin. A total of 12 points are still up to grab. But it will be very close with a gap of 6 points to place 16.
But yes, it seems quite unfortunate because, if I also consider Bayern Munich's performance throughout this season then at least Bayern Munich won't be easy to win the Bundesliga title this season because it seems like Tuchel doesn't fully fit here. Therefore, if I compare the past and at this moment, then I will conclude that there is still no strong guarantee for Bayern Munich to be able to maintain its top position until the end of this season.
I understand that Bayern Munich has not been very consistent this season. So it is hard to believe that they are not going to make any mistakes again. But at the same time, Dortmund has also not been very consistent this season. So it is also really hard to actually trust Dortmund as well. Even if Bayern Munich does make mistakes going forward in these final matches I would say that Dortmund is not going to be able to take advantage of that.
After all, we have to think about the probability versus possibility. It is possible that Dortmund will be able to win the title. But the probability indicates towards Bayern Munich.
