There are other clubs who are doing well in the Bundesliga except for Bayern Munich. So I will say that Bayern Munich will have to be careful. Otherwise, they are going to actually give up the first position on the table. Even though I think that is really hard to be happening. But I don't think it is absolutely impossible. After all, we all know how Bayern Munich started this season. They did not start the season well. And they cannot take things easy if they want to hold on to the first position on the table.
there are clubs with good teams in the Bundesliga. but as you can see, consistency of play as strong as Munich is very rarely seen in the Bundesliga.
however, Dortmund has always been obsessed with the player transfer business that benefits them. if Dortmund wants to beat Munich it can be done if they don't care too much about business and focus on chasing trophies.
