borussia dortmund will only continue to perform like this until end of season before this club can develop new talent again like before which still mystery to this day because Dortmund performance really very bad and if they not want to profit from winning title least improve performance of their players it would better than looking bad like now.
Even if things are currently in bad shape, I am sure borussia dortmund will provide news if they have another talented player with skill to scored and continue to improve the player talent so they can be sold in transfer market later.
I also not want to expect anything more from dortmund except to hope that this club can produce more talented young player after sell them to help improve strength of other club.
From the beginning, Borussia Dortmund only cared more about money than they also cared about producing the best players before they sell them again in the transfer market next season to other teams. So if Borussia Dortmund fans see that the team's performance has been bad and usually, it is normal because Borussia Dortmund doesn't really care about improving their performance. Because the concept they build in each season is to be able to produce the best players before the next season takes place, but they will definitely always aim for the UCL zone in the Bundesliga.
