It also was up against an extremely weak opponent. Even though Hertha didn't concede a goal for such a long time, everyone could see why they are by far the worst team in the Bundesliga. It was catastrophic. How they are handling the ball and the passing, everything is so bad and yet it took Bayern 70 minutes to score a goal. I think that perhaps it is still not over for Dortmund. If Bayern plays like that against the upcoming opponents and also against Leipzig, there is a possibility that they will drop points one more time. Whether Dortmund is ready or not then is another question.
Bayern created a lot of chances, but I don't see a problem in that they only scored in the 70th minute, sometimes it happens that the ball does not fly into the net, the most important thing is that they won. It would be good for Bayern to have a strong centre-forward like Haaland or like they used to have Lewandowski, in which case I think with so many chances created the score would have been significantly higher. I am sure that Bayern will be able to keep the championship.
