One more game for Borussia Dortmund to see if they will make it to the Champions League next season or they will have to settle for Europa league and this will mainly depend on if Frankfurt will be able to defeat Frieburg or at least draw them. I more positive that Dortmund will beat Holstein Kiel in their next game. So far Borussia Dortmund and Frieburg has had equal records in their last 5 matches, 4 wins and a draw, although the last time Frieburg lost was against this very Dortmund in a 4 - 1 defeat. Dortmund will be hoping for Frankfurt to do them a favour and I seriously hope Frankfurt does it for them because I want to see Dortmund in the Champions League next season.
You are right that Dortmund has been playing well lately just like Freiburg winning four games and drawing one of their last five. And fact is that Dortmund beat Freiburg pretty easily last time they played might give Dortmund fans bit more hope. You also look pretty sure that Dortmund will win their next game against Holstein Kiel.especially because Kiel has not been doing so well this season.
So it all depends on that game between Frankfurt and Freiburg. You are definitely not only one hoping that Frankfurt gets good result because you really want to see Dortmund in Champions League next season. It is going to be nerve wracking last day of games because Dortmund needs to win against Holstein Kiel and then hope that Frankfurt helps them out. Let's see if Dortmund gets their wish to play in Champions League.
