Who could step in for Köln?

General manager Christian Keller’s team is already scouting options. Priority is a centre-back with Bundesliga experience who can slot straight in. Candidates may come from the 2. Bundesliga or abroad, though Köln’s transfer budget is limited.

What happens next?

1. FC Köln plans to fill the defensive void with an incoming signing. Head coach Steffen Baumgart is open to flexibility – even shifting a full-back into the centre could be considered. Fans hope for a quick resolution so pre-season preparation isn’t disrupted.
