Dortmund are doing great at the moment. Dortmund is at the top of the points table after beating Bayern Munich. I think Dortmund won't be able to stay at the top of the points table for long because Bayern Munich will win the next matches very well and stay at the top of the points table.
Dortmund are at the top of the standings at the moment not after beating Bayern Munich, but this was obtained by Dortmund after Dortmund were able to beat Frankfurt at their own turf with a large score without any reply from Frankfurt. It was this victory that brought Dortmund to the top of the standings because at the same time Bayern Munich was defeated by Mainz so that Dortmund made it to the top of the standings after being able to win a lot over Frankfurt.
the difference with Munich is only 1 point. Dortmund will not be able to calm down in the hunt for the Bundesliga title. because the fight will be determined until the end of the season. we can see many clubs will fight for their targets this season. and Dortmund could be champions this season if they can be consistent. but Munich cannot allow that. because after being eliminated from several competitions, only the Bundesliga title is the only title that Munich can still get this season.
