"The Serbian Football Association (FSS) has appointed Drulovic as acting coach until a permanent one is named, most probably in late April or early May," the national association said on its official website on Friday.
"This is the best possible solution because Drulovic has earned his chance after achieving the historic success of winning the European under-19 title last year."
Drulovic scored three goals in 38 appearances for the former Yugoslavia and spent a combined nine years at Portuguese rivals Benfica and Porto, where won a total of five league titles and four cups.
After several low-key coaching jobs, he rose to prominence when he guided Serbia's unheralded under-19 side to a shock success at the 2013 European championships in Lithuania.
Drulovic's no-nonsense approach combined with a father-figure respect he earned among the players during the tournament could leave him as the prime candidate for a permanent deal after a plethora of other candidates made themselves unavailable.
Sinisa Mihajlovic, who failed to lead Serbia to the 2014 World Cup, turned down FSS president Tomislav Karadzic's appeal to return in a dual role after taking over at Serie A side Sampdoria in November following his acrimonious split with the national team.
Aleksandar Stanojevic, who had a relatively successful two-year spell in the Chinese first division, made a U-turn earlier this week after he seemed poised to take over while Dragan Stojkovic and Ljubisa Tumbakovic also snubbed the offer.
