Joseph Mermans (16 February 1922 in Merksem – 20 January 1996 in Wildert), usually referred to as Jef Mermans (nicknamed "The Bopster") was a football striker from Belgium, who played much of his career at Anderlecht, with whom he won 7 Belgian Championship titles and finished top scorer of this competition 3 times.
In the early 1930s, the young Mermans, along with a couple of friends, could not afford to become members of FC Antwerp. Eventually, the boys tried their luck at Tubantia F.A.C. (a small club in the Antwerp suburb) and managed to force themselves a way into the youth team.
Five years later, Mermans entered the first team. His progress caught attention of the federal coach and Jef was selected for a Belgium B squad match against Luxembourg in January 1939. At this point, he received twice in two years a proposal to play in the Beerschot team, but Tubantia Borgerhout refused.
On his arrival at Anderlecht, the Championship was quite erratic due to the World War II, but he helped Anderlecht in becoming a regular team. In 1947, Mermans was the key player in the conquest of the first Anderlecht title in first division as he scored 38 goals (succeeding to Bert De Cleyn as top scorer). At the peak of his career, Anderlecht received offers from A.S. Roma, Torino Calcio, Atalanta Bergamo, Real Madrid, S.S. Lazio and Atlético Madrid but refused them all.
In 1957, the Bomber, as he was called for his powerful strikes, left Anderlecht for the small K. Olse Merksem club in his native town. With him, the club promoted from 3rd to 2nd division and even finished 4th in 1960 for its first season at this level. Later on, the club was renamed Olse Mermans to celebrate the player.
The stadium in Merksem is named after him.
