He started playing football in the local club Vratnik from Sarajevo. After that, he played in FC Sarajevo, first in junior categories and then in the senior squad. With the senior squad he won the Championship of Yugoslavia in the season 1966/1967. In the season 1963/1964 he was the best striker of the Championship of Yugoslavia with 19 scored goals. In 1963 he was shortly in the Turkish football club Fenerbahce, but he returned to his home town of Sarajevo after only a month and a half spent in Istanbul.
