The 20-year-old Frenchman, who had a sensational first season in Germany, had scored an identical goal in the semi-final of the competition to eliminate Bayern Munich. In the Bundesliga, the "bumblebees" finished in third place with 64 points and a goal difference of 72-40.
Dortmund upset Bayern in a come from behind 3-2 victory. "It wasn't easy. The team earned it", said Dortmund president Reinhard Rauball, alluding to the difficulties players faced after the bomb attack on the team bus in April.
Dortmund are looking to win the trophy for the first time since 2012; Frankfurt are gunning for their first success since 1988. We have been here before and that gives us a certain calm, but we are facing a tough opponent. "It will be a tight affair". Kovac has a lot of confidence in his squad and they will throw everything at Dortmund in the 2017 DFB Pokal Final.
Tuchel responded by switching from a 3-3-2-2 formation to a 4-5-1 formation with Aubameyang, the Bundesliga's top scorer this season with 31 goals, as the loan striker.
Shinji Kagawa created the first big opportunity of the second half when he flashed the ball across goal from the left on 50 minutes, with Frankfurt's defence stretched to its limit trying to stop Pulisic from nudging his men ahead.
Dortmund are the only team to have reached four straight German Cup finals but have missed out on the trophy since they won it in 2012. Will the rumors affect Dortmund against Frankfurt?
The Black and Yellows were made to wait another quarter of an hour before they finally got their opening, when Pulisic was clipped by Frankfurt goalkeeper Lukas Hradecky inside the area. They have been great to watch, they are very courageous and it is unpleasant to defend against them.
