Edin Dzeko marked his record-equalling 94th Bosnia-Herzegovina cap with an assist in his country's 2-1 victory over Northern Ireland in their Nations League opener.
The 32-year-old Roma striker, who has now made as many international appearances as Emir Spahic, provided the cross that Haris Duljevic turned home nine minutes before the break.
Northern Ireland goalkeeper Bailey Peacock-Farrell was then involved in a second-half mix up with Watford defender Craig Cathcart on his first international start, which Elvis Saric capitalised on to add a second in the 64th minute.
Will Grigg grabbed a stoppage-time consolation for the hosts but it was not enough to deny ex-Real Madrid and Barcelona midfielder Robert Prosinecki a victory in his first competitive game as Bosnia-Herzegovina's coach.
Ten months after a controversial penalty in a play-off against Switzerland at Windsor Park ultimately cost them a World Cup place, Northern Ireland were denied a spot-kick of their own inside 40 seconds when Ervin Zukanovic appeared to trip George Saville.
That came during a bright Northern Irish start which ended with Duljevic ghosting past two defenders to convert Dzeko's left-wing cross.
Northern Ireland continued to push after the break, with Ibrahim Sehic denying Stuart Dallas and then making a point-blank save from Kyle Lafferty.
Despite the hosts' pressure it was Prosinecki's side who grabbed the next goal when Cathcart's header back to Peacock-Farrell failed to reach its intended target before Saric nipped in and made it 2-0.
Grigg's neat finish halved the deficit in the 93rd minute but when presented with a chance to snatch a draw the substitute fluffed his lines, leaving Michael O'Neill's side to rue their wasted opportunities.
What it means: Prosinecki up and running
Bosnia-Herzegovina have only ever reached one major tournament in their entire history, but with players like Dzeko and Juventus' Miralem Pjanic in their squad, they are hopeful they can reach Euro 2020. Prosinecki was in charge of an Azerbaijan team that lost twice to Northern Ireland in the 2018 World Cup qualifiers, but he exacted a modicum of revenge.
Pat on the back: Duljevic the difference maker
Duljevic had never scored for his country before arriving at Windsor Park but he produced a clever run and finish for the first goal. And he nearly scored a second late on too, only to be denied by the woodwork.
Boot up the backside: Cathcart culpable
Northern Ireland defender Cathcart has been part of a strong start to the season for club side Watford, yet he had an afternoon to forget. He should have dealt with Dzeko's near-post cross for the Bosnians' first goal then let Saric in with a weak header back to his keeper.
