Don't be too confident because Borussia Dortmund are also targeting the same thing, namely the victory to close their points acquisition in the standings. Union Berlon are playing very well but that doesn't mean they can underestimate Borussia Dortmund. They still have to be wary of what Borussia Dortmund will show later. I see Borussia Dortmund have the spirit in this match, they will even chase the goal until the final whistle is sounded like in the match against Bayern Munich last week.
There is no way to underestimate a team like Dortmund. Maybe Dortmund can't play consistently well. But often they surprise everyone by performing well. Undoubtedly, Union Berlin's performance is better than Dortmund this season. Even then, if Union Berlin is not able to perform well in the match, they will lose points against Dortmund.
Maybe in this case the concentration and individual players can also be one of the determining things.
Even though it is clear that Union currently has a good performance, it is still difficult if you look at the condition of the players.
We know that Dortmund's squad is definitely better on an individual basis and I'm pretty sure this can be the difference in the game.
On the other hand, Dortmund's experience with a tight schedule clearly dominates because it can be said that this season is the first time the union has had a fairly tight schedule because it is in the Europa League and of course this requires extra energy in managing the squad in rotation of players.
