Roger Claessen (27 September 1941 – 3 October 1982) was a Belgian footballer who played as a forward. He finished as the top scorer of the Belgian League with 20 goals (along with Paul Van Himst) in 1968 while playing for Standard Liège.[1] He played 17 times with the Belgium national team between 1961 and 1968, scoring seven goals. Claessen made his international debut on 20 May 1961 in a 2–1 defeat to Switzerland, and he scored.
