Kerala's love affair for football started long before I-League or Indian Super League (ISL) came into existence.
They had FC kochin, the famous Kerala Police team before Viva Kerala came into existence. The state may not have had much luck in terms of long-term top-tier representation due to financial issues suffered by various clubs over the years. But in recent years, Kerala Blasters and Gokulam Kerala have managed to bring back the notion that the people still want to be involved in all things football.
Naturally, the people have supported movies that involve football as well.
