Dortmund was able to reach the finals last season, but got defeated by Madrid. Dortmund is very experienced in UCL and I believe that they will go far this season. Barcelona is in their best form and one cannot be underestimated, because they have scored a lot of goals this season. This shows that their attack is very active. However, the match is gonna be one of the best in the round of 16.
Borussia Dortmund last season had their best European campaign since 2013 that they last reached the UEFA Champions League competition and that's made a lot of people to back them to record another impressive European campaign despite their poor performance in the German Bundesliga this season. The first leg of their round of 16 game in the UEFA Champions League semi final is going on at the Signal Iduna Park with Dortmund leading with a goal to nil. I think they'll win tonight game and ultimately win the tie
