Focusing on the Champions League too much and having problems in the Bundesliga on one hand isn't very ideal for Dortmund at all. Dortmund's main target must always be to finish the season in top 4 at worst. Because the Champions League is like a tradition for Dortmund as they can normally finish the season in this area easily.
I see no problem by focusing too much on UCL. UCL was also giving dortmund additional income too. It will be very beneficial for the club as well. This is also the main reason dortmund puts more effort in UCL instead of bundesliga.
We are still long way to go till the end of season but the different thing when it comes to the how much money that is going to be received by dortmund. Terzic is still having enough chance to push dortmund to go up.
It was not lucky enough in the bundesliga but it doesn't mean dortmund played so poorly in any game. I know some would debate whether dortmund has chance to get the UCL spot by finishing at the top 4 or not.
But right now things are going really badly for them about this topic. While Stuttgart and Leipzig are performing much better Dortmund will need to work much harder than this. As there is a long time to go for next round games in the Champions League Dortmund had better work on their weaknesses in the Bundesliga.
I bellieve stuttgart and leipzig are going to decline soon. Im concerning about the news of guirassy to leave from stuttgart. This is going to affecting the performance from the club a lot. Guirassy was the only guy who can carry the club and it's all what dortmund need.
The team can take it as an opportunity to replace stuttgart's position. Dortmund got the job done in UCL. It must be doing even better in bundesliga. There is still enough time to improve.
