He was an important member of the memorable Sarajevo squad that won the 1984–85 Yugoslav First League, which earned him a move that summer to Red Star Belgrade.
[3] By then, Sarajevo had already lost many of the championship winning squad of 1985, so a year later, Musemić moved abroad again, this time to the Netherlands by joining Twente.
[6] Before retiring, Musemić played in Germany between 1992 and 1994 with SC Pfullendorf in the Oberliga Baden-Württemberg where he got the chance to show his scoring skills by netting 16 times in 32 matches.
[2] Later, after the break-up of Yugoslavia, in 1995, he played in the first half of the first ever official match of the Bosnia and Herzegovina national team, away against Albania.
While at Sloboda, Musemić also had good success, finishing 2nd in the 2015–16 Premier League season and being the 2015–16 Bosnian Cup runner-up.
[11] In the 2018–19 season, he had for a second time in his career won the Bosnian Cup after Sarajevo beat Široki Brijeg in the final on 15 May 2019.
[16][17] It was that same season in which Željezničar also beat Sarajevo 5–2 at home on the Grbavica Stadium on 31 August 2019, with Musemić getting most of the blame for the team's loss.
[20] Musemić oversaw his first loss as Tuzla City manager against his former Sarajevo, in a semi-final cup game on 7 April 2021.
[26] On 27 July 2023, it was announced by Igman that Musemić had left the club by mutual consent, two days before the start of the new season.
