Karl Odermatt (born 17 December 1942 in Lucerne) is a Swiss former footballer who played for FC Basel and BSC Young Boys throughout the 1960s and 1970s. He played as a midfielder or striker and is generally regarded as one of the best players ever to have worn the FC Basel shirt. He played through, what is now thought to be, Basel's golden years under trainer and manager Helmut Benthaus with team-mates such as Paul Fischli, René Hasler and Ottmar Hitzfeld.
As a small child “Karli” Odermatt grew up in Lucerne and later his family moved to Basel. A coach from the FC Concordia Basel youth system discovered him on a school football field, invited him to a club training and just a few days later he started playing in their youth team. Later he played in their first team in the 1. Liga.
“Karli” Odermatt signed for FC Basel in 1962 and in his debut, in September, against FC Lugano he scored two goals. In his first professional season, under manager Jiří Sobotka the mainly amtature team lifted the Swiss Cup, winning the final 2:0 against the favorites Grasshopper Club Zürich. Two more cup wins were to follow during Odermatts time at the St. Jakob Stadium. During the summer of 1965 Helmut Benthaus was signed as player-manager and Odermatt won his first league-winners medal in 1967. Four more league titles followed, in the years 1969, 1970, 1972 and 1973.
Odermatt was also a Swiss internationalist, and earned 50 caps in his ten-year international career. He played mainly in centre midfield alongside Köbi Kuhn, and played in all three games at the 1966 World Cup. He scored his first of ten international goals against England at Wembley Stadium on November 10, 1971.
Odermatt has two daughters (Jacqueline and Patricia) from his first marriage and two sons (Andreas and Daniel) from his second wife.
