Dortmund haven't had a great start to the season that's true but I think we'll see a stronger consequence of them for the rest of the season. Dortmund had a trend in previous seasons of always finishing in 4th place and it will happen again this season. Dortmund temporary ranking in the standings table is ranked 6th and the difference in points from the top 4 is only 2 points so one game in the future will be able to change Dortmund position in the standings table. dortmund have swallowed 6 defeats in the 15 matches they have played so this is a bad record for them because in 15 matches they have swallowed 6 defeats.
Dortmund trend every season with finishing at top fourth standing position and seems little possible how can compete and make Bayern Munich loss dominance in Bundesliga, I think bad habit with star player transfer they have in every window transfer open and can't back up with the same level player reserve become problem with Dortmund inconsistency in domestic league.
Current Dortmund standing position right now at 6th and behind 9 points from Bayern Munich, still have possibility with Bundesliga tittle but if can't consistency performance I don't think habit finished in top fourth standing become easy for Dortmund in this season.
