William Milovanovic

Milovanovic hails from Biskopsgården in Hisingen, Gothenburg. He started his youth career in IF Warta and Eriksbergs IF before joining BK Häcken at the age of 12, where he continued progressing through the academy ranks. A Sweden youth international, he participated in the 2019 UEFA European Under-17 Championship. He made his senior debut for Häcken in the 2020–21 Svenska Cupen, playing all three group matches as well as the semi-final against Västerås, all in February and March 2021. He then made his Allsvenskan debut in May 2021 against Örebro. However, his senior career in Häcken did not last long. Following loans to Norrby IF in 2021 and Utsiktens BK in 2022, he had to leave Häcken. Milovanovic first opted for a transfer to the Slovenian club NK Koper. After playing a handful of games there, he returned to Utsiktens BK where he played the latter half of the 2023 Superettan. Milovanovic was then picked up by 2024 Allsvenskan newcomers GAIS. In May 2024, he was one of the instrumental players in the Gothenburg derby where GAIS beat Häcken. Though GAIS rotated their players throughout the season, Göteborgs-Posten pointed out that their avergage point score was higher when Milanovic was played. His performances in 2024 spurred rumours about him joining one of the major Swedish clubs, such as AIK.

Being of Serbian descent, Milovanovic was considered by Serbia U21.
