Leverkusen should have longer spells on the ball and look for Schick from García's deliveries. Köln can disrupt that first pass and release a wide runner before the visiting defence retreats. A saved shot or short corner may leave the next contact in a more useful position than the first attempt.
Krauss can move a regain into Maina and Said El Mala, with Bülter and Castro-Montes supporting the next delivery. Leverkusen's García-to-Schick route remains strong, but their recent retreat and second-ball defending have left space for opponents. Ache has returned to Köln training but was not ready to start after missing the last match; the current home route uses players who played recently. Badé is available for Leverkusen, while Kofane's training return does not displace Schick's observed role.
Köln have the rest and receiving options to turn at least one regain or restart into an answer. I'm siding with Köln to avoid defeat.
