Born on 17 November 1994 in Banja Luka, Anjur joined midway through 2010/11 as an Under-16 and played five times in midfield for the youth side that campaign.
His technical strength makes him a good asset in building attacks although his youth team appearances in 2011/12 were limited to eight starts and six games as a sub. He was handed his reserve team debut at the end of the campaign, followed in the summer by a two-year professional contract. He has played for Sweden at Under-17 level.
Osmanovic is currently on a season-long loan at his former club, Larje-Angereds I.F.
