Because this is the Final, both of teams still have the possibility to win, also based on the head to head these both teams are quite equal. But Leipzig this season is so great, they are not easy to beat. Also, after being able to beat Bayern Munich at the Allianz Arena some time ago, Leipzig might also be more motivated to win. Even so, somehow I also believe in Frankfurt, let's hope they can win in that game.
The head to head statistics aren't really relevant in this game. What does head to head help anyone when you are playing a really bad season? When head to head would have any meaning apart from the form, this Bundesliga season wouldn't have seen so many surprises all the time.
Leipzig has played a much better season with 16 points more than Frankfurt, but Frankfurt has shown that they are a different team in the DFB Pokal this season. Both had some strong games like Leipzig against Dortmund and Freiburg or Frankfurt against Union Berlin. Kolo Muani is an incredible player who can overcome Leipzig's defense. With good team work and the individual strength due to Muani, Frankfurt has all chances to win this game as well even when Leipzig is the favorite.
