Player & Tactical Analysis

Dortmund’s back-three with attacking wing-backs (Couto/Svensson) should pin Union’s flanks, freeing Brandt to feed Guirassy/Beier. Defensive absences thin aerial protection, so Anton’s positioning and Sabitzer/Größ’s counter-pressing are key to rest-defence stability.

Union under Baumgart keep a compact 3-5-2, inviting crosses and springing direct counters through Ansah’s power runs and Ilić’s hold-up. Trimmel’s early crosses and Skov’s set-pieces are their clearest creation levers.
