Input: Question: When was the team that Nikola Zigic first began playing football with founded? Passage:Zigic was born in Backa Topola, in what was then SFR Yugoslavia. He began playing football as a youngster with AIK Backa Topola, and scored 68 goals from 76 first-team matches over a three-year period in the third tier of Yugoslav football. Military service took him to Bar in 2001, where he was able to continue his goalscoring career with the local second-level club Mornar. A brief spell back in the third tier with Kolubara preceded his turning professional with First League side Red Star Belgrade in January 2003. He spent time on loan at third-tier Spartak Subotica before making his Red Star debut later that year. Despite suggestions that his height, of , made him better suited to sports other than football, Zigic ended the season as First League top scorer, domestic player of the year, league champion and scorer of the winning goal in the cup final. He won a second leaguecup double in 200506, a second player of the year award, and finished his three-year Red Star career with 70 goals from 109 appearances in all competitions.
