De Kolenputters KFC Winterslag
Belgium · Founded: 1923
KFC Winterslag was a Belgian football club from Winterslag, a mining district of Genk in Limburg, founded in 1923 as Winterslag Football Club and registered with matricule number 322. Playing in red and black at De Noordlaan stadium, it was the club of the local coal miners, which gave it the nickname De Kolenputters. It became Koninklijke Football Club Winterslag in 1972.
The club's big rise came in the 1970s, when it climbed from the third division to the Belgian top flight, where it spent nine seasons in total. Its finest moment came in the 1981–82 UEFA Cup: Winterslag knocked out Bryne of Norway and then the famous Arsenal on away goals, before losing to Dundee United in the next round.
In 1988 Winterslag merged with its local rival Waterschei Thor to form KRC Genk, which kept Winterslag's matricule number 322 and went on to become one of the leading clubs in Belgium.
