KELLER sponsors the FC Stapo Winterthur in the form of jerseys. In Winterthur's corporate football league, the city police are a permanent fixture and even have a chance of promotion in the new year. Like FC Winterthur, the club now wears the KELLER seagull on its jersey.

During FCW's home games on the Schützenwiese, the city police actively support FC Winterthur and along with the city of Winterthur we have a reliable partner for our new building project «Diamant».
