Dortmund beating Leverkusen was a step ahead of them ending top 4 in the league left with 1 match to determine where they end up. If Dortmund can successfully win Holstein Kiel in the last game of this season what they wish for is SC Freiburg to lose or draw, SC Freiburg will be playing against Eintracht Frankfurt who are 3rd place also competing in this final game to qualify for Champions League, they can't go easy on SC Freiburg, that last game will determine for this three teams who makes it out of the leading top 4.
Few weeks back Dortmund was sitting in 10th position but now they are fighting for top 4 what a surprise. No one expected them to improve in this manner, they really surprised everyone, they improve their game and made sure they didn't drop anymore points and that is why they were able to get so close. Their top 4 hope could have shattered if they had lost against Bayern Leverkusen but the win actually kept it alive. They just have to win their game and hope Freiburg drops point. They started poorly and ending it well even though they didn't challenge much at least this development is something for them and it might help them have a better performance next season.
I was also surprised to see how Dortmund performed in their last five matches; they won all their five matches including a 4-2 win away from home against Leverkusen which was the match I was thinking will be obstacle for Dortmund against their effort of playing in the Champions League next season, but they won the match comfortably and gain more confidence to continue their winning streak against Holstein Keil in their last Bundesliga match of this season; I am very sure that Dortmund will win the match and might have advantage because Freiburg have a tough opponent to play against in their next match. They Freiburg need to defeat Frankfurt that is also looking for way to seal their Champions League spot if they can play either a draw against Freiburg. This means that the match will be very tough because both the teams needs the three points, while Dortmund will wait for who will win if they are also able to defeat Keil in their last match.
