Borussia Dortmund vs Manchester City prediction (Over/Under)

2nd leg game, first one was won by City 2-1. I think such result suits us to expect another 3 goals. Dortmund will have to score, that's bad news for their defense, which is simply very unreliable this season and lately as a whole. I have no doubts that Citizens also won't come on the pitch just to defend the lead, that's too risky, advantage is too slippery and knowign hosts' defensive issues, visitors surely will look for a ways to score an make life easier. That should make game more open and goals must happen. Cheers
