Bayern Munich and Borussia Dortmund were dominating clubs in Bundesliga, but recently we have transition of power and few clubs are improving their quality which helping them for having good results and top spots in league we have good fight from Bayern Munich, but Borussia Dortmund is struggling and have bad time with in last season they ended on 5th spot now in this current season we have them again on sixth even we have long way to go, but things are surely looking for improvement and having increase in quality.
Bayer Leverkusen is surely now better club with their way of performance and results now in coming round we will be having big game which is going to play at the Dortmund headquarters and this will give view how things will be gone for both clubs because Bayer Leverkusen looking for challenging Bayern Munich and Dortmund looking for having better result and spot in league table.
Dortmund may still have a chance to improve their position in the standings, the points difference is also not far. But for the trophy competition, I think Dortmund may be a little behind. It will be difficult for them to catch Munich who are already leading or Leverkusen.
They missed a few seasons ago to win the title when their performance was good. And last season they experienced a decline in performance. At the moment, they don't seem much different. There is still a chance to improve their position, but I am not too surprised by what Dortmund will achieve.
