We know Dortmund are more experienced in this competition and because of that they are not an opponent to be underestimated. Even PSG's size certainly won't be able to win easily and instead Dortmund will put pressure on them. I think the difference in squad depth will not apply in the Champions League and the most important thing is the mentality of each team itself.
Dortmund proved to be the champions of the hellish group at the start of the season and stopped other strong teams such as Newcastle and Milan. Now they will face the same opponents as in the previous group and I am sure they will have no problem getting a ticket to the Champions League final.
The UEFA Champions League is not some random average competition, it's top and require the best among the best to win the title. Luis Enrique and Edin Terzic are both good coaches, they know the weaknesses and strong grounds of their opponents and they ensure they're accumulating points and meeting targets every season. Borrusia Dortmund are experienced, also is Paris Saint-Germain. These are the dominadable clubs in their perspective league and we hoped to see their very best performance in the UEFA Champions League this season.
