Dortmund are not very lucky with their schedule in the recent times. Because their next opponent in the league is Union Berlin in an away game. Considering that Union Berlin are still the leader in the standings now Dortmund have a very tough game ahead. Dortmund defeated them here by 3-0 last season actually. And they didn't have Haaland in that game due to an injury as well.
Now Union Berlin are stronger and more motivated of course but let's see if Dortmund can still keep an advantage against them psychologically. I'd rather bet on both teams to score @1.71. I don't think any of them will have big difficulties in scoring at least one goal.
Union Berlin formally now has the best defense in the Bundesliga, while Borussia's attack is far from ideal. Both teams are in the top group and it seems to me that they will play more cautiously than with the intention to get three points at all costs. I think betting on BTTS is very risky in this meeting.
Agree with what you said because indeed 9 matches have been run this season they are the club that has conceded the fewest goals because only 6 goals have been in Ronnow's goal.
But indeed this can still change because even in this case Union is still very good but I am a little doubtful whether they can still be consistent or not in the upcoming matches.
