Looks like Dortmund is making a comeback bro, the current score is 1-2 with an aggregate score of 2-3. Very bad. 
In the Arsenal match I have an assumption that Arsenal can lose in this match. Because even though they lose, Arteta is very safe to be able to continue the match to the next round. But if all bettors assume Arsenal will lose in this match, I am sure the result will be the opposite and be a draw as you predicted.
Dortmund makes it to the quarterfinals at the end of the game after their comeback. Congratulations to Dortmund, they deserve to be there compared to their opponents because they get eliminated by Lille, it will be very shameful despite their inconsistency this season.In the Arsenal match I have an assumption that Arsenal can lose in this match. Because even though they lose, Arteta is very safe to be able to continue the match to the next round. But if all bettors assume Arsenal will lose in this match, I am sure the result will be the opposite and be a draw as you predicted.
I don’t think Arsenal can lose this match tonight, and even if they end up losing the match, they have already qualified because conceding seven goals will look stupid for Arsenal.
Arsenal will even win because they will be playing at the Emirates Stadium in front of their fans, and Martinelli is back to give Arsenal attack more strength.
