Dortmund almost became German champions last year and only some sort of curse prevented them from beating Bayern. So Dortmund is a very strong team that can play on equal footing with the strongest groups, which is proved by the fact that from the group with PSG, Newcastle and Milan they went to 1/8 Champions League.
They should have won the match with PSV, but the referee awarded an extremely controversial penalty, which should not have been awarded, because the Dortmund player played into the ball, not into the feet of the PSV player and because of the referee's mistake Dortmund lost 3 points.
There is no doubt about Borussia Dortmund strength, and they surely can go into next round with their performance at home in second leg match even I am also feeling this penalty was not right, but now all ended with draw and good for the German giant to improve their performance in coming weeks for having good chance for the next round qualification PSV also done good, but they need more experience and quality performance for this level.
Overall both teams done good job in this game and having equal chances but still I have feeling Borussia Dortmund can do better, but they are having some problems in last few weeks which are not allowing them for having enough goals but still their chances are good for having good end in both leagues.
