Borussia Dortmund's clinical finishing proved too much for Union Berlin as they cruised to a comfortable 3-0 victory at the Stadion An der Alten Försterei. Dortmund's opener came from the penalty spot, with Emre Can converting in the 10th minute after a foul in the box. Despite Union Berlin enjoying 56% possession, Dortmund out-shot the hosts 15 to 10, with a higher expected goals of 1.84 to 1.24.

The key tactical reason behind Dortmund's win was their ability to transition quickly from defense to attack. Dortmund's players were consistently able to win the ball back and immediately look for opportunities to counter, as evidenced by their 44% of possession. This allowed them to capitalize on Union Berlin's high defensive line, with Schlotterbeck's goal in the 53rd minute coming from a well-weighted through ball that split the defense.

In contrast, Union Berlin struggled to break down Dortmund's organized defensive structure. Despite their territorial dominance, they managed just 3 shots on target, with a significant portion of their attacks breaking down in the final third. This was a tactical failure, as Union Berlin were unable to find the right creative outlets to unlock the Dortmund defense.

The visitors' clinical finishing and efficient counterattacking proved the difference, as Beier's late goal capped off a comprehensive victory for Borussia Dortmund.
