I think Freiburg has good chance to win this one. Dortmund are very poor in terms of goal scoring right now. I feel if Freiburg manages to score 2-3 goals then I don't think Dortmund have a chance to win or draw. I also agree that Freiburg and double chance seems to be a very good bet here. It's gonna be a good shot as Dortmund has really let down so far since the start.
I haven't checked the odds for these two teams, but if I refer to Asian handicap betting, the match between Freiburg vs Dortmund, the away team is superior with handicap odds of 1/2:0. Freiburg has a good chance of winning the match, because they will play this match in front of their own public. However, that doesn't mean that Freiburg will win the match easily, especially since they previously lost in a landslide by Stuttgart with a landslide score of 5-0. IMO, it looks like their defense is a little problematic. Apart from that, there are several Freiburg defenders who are absent due to injury.
On the other hand, Dortmund experienced a campaign with unsatisfactory results in their 3 matches. In fact, they seem to be having difficulty scoring goals. The last two matches they played ended in a draw. but after the international break, maybe their performance will improve. However, I have a prediction that Dortmund will win the match against Freiburg. It is very likely that Edin Terzic will rotate some of his players. I suspect that Niclas Fullkrug will be the main starter in the next match. and possibly, he could be a solution to the problems that occur in the Borussia Dortmund squad. So, to find out more, let's just wait for these two teams to meet.
