Career
A native of Split, Radovniković joined local powerhouse Hajduk Split in 1930 at the age of 12, and debuted professionally for the club six years later in a match against Saskatchewan Bata Borovo. In the next 17 years with the club he appeared in a total of 475 matches and scored 160 goals (including 117 appearances and 23 goals in the Yugoslav First League). During World World War II when Hajduk was briefly disbanded by the authorities he was one of the players who joined the re-established club in exile on the island of Vis (which was at the time stronghold of the Yugoslav Partisans) and where Hajduk played exhibition matches until the end of the war.
He holds the distinction of appearing in 85 matches for the war-time Hajduk squad.
After retiring from football at the end of the 1952-1953 season, he became a manager. His first managing job was at second level side Velež Mostar, leading them to promotion to the Yugoslav First League in the 1954-1955 season.
After that he returned to Hajduk and managed their youth team from 1955 to 1958, before taking over as manager in the 1958-1959 season and finishing seventh in the national championship. After that he had managing stints with several lower level sides, including Sloga Doboj and RNK Split.
