They are performing really well in the Champions League, they are not playing that well in their own league but their performance in the Champions League is quite good. They will face Barcelona in the next match, we will probably watch one of the best matches of the year.
They may not have much chance against Barcelona, I think they will fall back in the rankings after that match. The Champions League is going very exciting this year

Everyone becomes really serious following the competitive nature of these elite leagues. Borrusia Dortmund are not only the elite side that's having a competitive good run in the UEFA Champions League. We have other competitive clubs that are closing in to accumulate good points on the table. Borrusia Dortmund faces Barcelona next and that's simply a tough run down I'd you ask me. Nuri Sahin is having a close watch about the tough oppositions this season, ranking 4th position on UCL table and also in the race for Bundesliga title, watching him having whole priorities to handle.
Dortmund are performing great in the ucl more than the league, but I don't think they will have the opportunity to defeat Barcelona in their next ucl competition because Barcelona are performers great in both the league and the champions league this season, and I just see that Dortmund are just trying in the ucl more than the Bundesliga title, but I think that is because they see they can't achieve the trophy anymore, so they focus more in the ucl and see if they can But anything may happen against Barcelona and Dortmund. I see that Barcelona has started losing form in the league because they are giving real madrid more opportunities to overtake them in the league this season, drawing and losing games with small clubs in te competition. Dortmund are doing well in the ucl and they can probably give Barcelona a tough time before they can defeat them or draw game. Let us watch and see how the game will be ended and see who will be the favorite achieve the three point.
