After making his professional debuts with local club Budućnost, Brnović signed with national giants Partizan in 1991, helping the latter club to back-to-back national championships, with the addition of two cups. In the 1992–93 season, as it won the league and lost the domestic cup to city rivals Red Star, he scored a career-best six goals (the team netted 103).[2]
In 1994, Brnović moved abroad and joined RCD Espanyol in La Liga – then known as Español. A starter in four of his six seasons in Spain, he left after a poor individual campaign (only one game in the league), which ended with conquest of the Copa del Rey.[3]
Brnović came out of retirement in 2006 to play one season for Montenegrin club Kom.
International career
Brnović represented Yugoslavia on 27 occasions, his debut coming on 20 September 1989 in a 3–0 friendly win with Greece in Novi Sad. He also appeared during the UEFA Euro 1992qualifying stage as the nation made it all the way to Sweden. He was included in the final tournament,[4] but the team would be suspended due to the Yugoslav Wars.
On 5 March 2007, Brnović was appointed assistant manager of Montenegro.[6] On 8 September 2011, he became head coach after Zlatko Kranjčar was sacked, leading the side to the Euro 2012 playoffs, where they lost 0–3 on aggregate to the Czech Republic.[7]
On 17 December 2015, it was announced that Brnović's contract, due to expire at the end of the year, would not be renewed.[8]
