Dortmund should see more of the ball, but possession alone may not settle this match. Sabah can pack the centre and release Parris or Mickels quickly when they win it back. The gap between Dortmund reaching the final third and finding clean central shots is the key.
Dortmund's back three and wing backs can pin Sabah in, and Guirassy gives their crosses a target. Sabah's route runs through Lepinjica or Rakhmonaliev recovering a second ball, Parris accelerating behind a wing back and Mickels receiving directly. That outlet helped them beat Slavia, although Pokatilov also had to make six saves as Slavia created chances.
Sabah's recent central group remains available, while Dortmund have lost Karetsas and must manage a short turnaround and travel. Dortmund found better chances after changes against Bodø, but their slower progression against Union and Bodø gave compact opponents time to reset. I expect Sabah to spend long spells defending yet retain enough direct threat to keep the contest close. That's why I'm siding with Sabah.
