Association football is the most popular sport in Bosnia and Herzegovina. It dates from 1903, but its popularity grew significantly after World War I. At the local level, FK Sarajevo (1967 and 1984), Željezničar (1972) have both won the Yugoslav Championship. The former Yugoslav national football team has included a number of Bosnian players, such as Josip Katalinski, Blaž Slišković, Dušan Bajević, Enver Marić, Mehmed Baždarević, Ivica Osim, Safet Sušić, Vahidin Musemić and Mirsad Fazlagić.
