after the first half was over borusia dortmund had taken a 1-0 lead despite psv being the host. possession of the ball is not a benchmark as a measure to win the match but a dangerous shoot on goal can be a benchmark because it means that the attack is very effective. if only possession of the ball shoot on goal does not dominate indicating possession of the ball in its own area of the playing field.
Borusia Dortmund did appeared to me like they were going to win this game but then they ended the game in a draw, taking a look at how the group stage games were like for them, they had tough teams around them yet Dortmund was still able to finish top of the group which could means they were actually a good team and in this match facing PSV who isn't a weak team wasn't an easy one because PSV did played well too.
I do say that playing so well isn't too important as the winner remains the one who goes home with the trophy, Dortmund have an advantage because they have gotten an away goal which keeps them ahead of PsV especially if PSV is unable to get a goal when they visit them, they may have to end their journey in the champions league, a 1-0 for Dortmund in the next match will mean going to the next stage, meanwhile inter Milan is about getting pass the round of sixteen and may find their self at the finals again this season that's if other teams get kicked out and inter is able to make it to the finals.
