Leipzig is not only the favorite because of the odds , they have some really high quality players in there team.
But i guess we will see a lot Frankfurt fans in the Olympic Stadium in Berlin and if there are enough they can push there team.
I dont think when Leipzig will win this final that they destroying Frankfurt.
The best outcome would be overtime and then get into the penalties.
The hallmark for Frankfurt is this.
Just like last season when their fans packed Camp nou when they met in the Europa League and so they were in the final and won against Rangers for that. They have a lot of loyal fans for Frankfurt which indeed this can also be an added strength due to the atmosphere generated which of course sometimes damages the mentality of the opposing players.
Right now, even though Frankfurt is not really the favorite, I think they can still do it, although it's a little difficult.
h2h for now in the bundesliga they are also even but in these 2 meetings Frankfurt can be said to be superior in goals so it is possible that this will also be another passion for them.
