Robert Prosinecki claimed a victory in his first competitive game in charge of Bosnia-Herzegovina, for whom Edin Dzeko won a 94th cap.
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.
