Looks like Dortmund is more focused in the champions league game than they do in their domestic league, seeing their incredible performances so far in champions league tells a lot, they may not be in a good form when it comes to Bundesliga title race but could go as far as reaching the final game in champions league competition. Still Dortmund has a great chance of finishing up 4th in the league side because of the points difference between, Stuttgart, Leipzig, Wolfsburg, and M'glabach ranges from 1-3 points so very likely will finish in the top 4 at the end of the season.
Focusing on the UCL and ignoring the Bundesliga was a big mistake made by Dortmund, even though they could beat Lille in the round of 16, they will most likely face Barcelona in the next round. Dortmund must take a more realistic look at their abilities including the chances in the UCL which leaves strong teams from different Leagues.
Dortmund must maintain their position in the Bundesliga in order to finish in the European zone in anticipation of failing in the UCL.
Dortmund are currently unable to maintain their position in the Bundesliga by focusing on the UCL, which has led to a significant drop in their points. If Dortmund can beat Lille, the next match will be even more challenging for them, and if they face Barcelona, Dortmund's chances of winning will be greatly reduced, and they may even be eliminated from the Champions League. If Dortmund fails to meet their expectations in the UCL, they will not have a chance in the Bundesliga either, and if Dortmund cannot stay in a good position in the points table, they will not be eligible to play in the Champions League next season. Therefore, they may not be able to compete with the strong teams in the Champions League this season, so they should focus more on the Bundesliga so that their position for the next season is good.
