A compact stadium, a passionate fanbase and one of German football's most distinctive city-club relationships.
1. FC Köln is inseparable from the identity of Cologne. Founded in 1948, the club quickly became one of Germany's leading sides and won the inaugural Bundesliga championship.
The RheinEnergieStadion is a compact four-stand ground with excellent sightlines and a roof that concentrates the sound towards the pitch.
The Südkurve provides the most intense support, but the atmosphere extends across the stadium when the club's anthem begins.
Before kick-off, supporters sing 'Mer stonn zo dir, FC Kölle'. Sung in Kölsch dialect, it is one of German football's most memorable pre-match rituals.
Keep an eye out for Hennes, the club's famous live billy-goat mascot and one of the most recognisable traditions in European football.
