It's the closest club in my area. All the people around me are Borussia fans. I've been an Inter fan for 19 years now and finally Inter comes close to my area and then the freaking COVID happened so I can't be in the stands of the Borussia Park...
Coming back to your question, Borussia will not be an easy opponent. Their coach Rose is a pretty good coach and their team has pretty good players too. Right now they have a pretty bad phase and the injury of Zakaria is one big reason for it.
But still, their strikers (Plea, Thuram and Embolo) are pretty fast and dangerous and their defence around Elvedi, Ginter and Sommer are very decent, too.
If we don't take them serious from the start, we will lose this game. And that is what I am afraid of because Italian clubs tend to undervalue German clubs (just think about 2011 the game against Schalke
)
