Markovic, 20, is tipped join Liverpool from Portuguese champions Benfica after the Premier League club reportedly activated his release clause.
The Serbia international winger, who made his debut as a 17-year-old against Armenia in 2012, only arrived in Portugal at the start of the 2013-14 season after joining Benfica on a five-year deal from Serbian powerhouse Partizan Belgrade.
Despite spending just one season in the Primeira Liga, Drulovic - interim coach of the national team following Sinisa Mihaljovic's decision to take charge of Sampdoria in November - said Markovic's proposed move to Anfield was the right decision for his career.
"Markovic made an excellent season at Benfica last year, he evolved a lot," Drulovic told Portuguese radio station Radio Renascenca.
"It'll be good for him and Benfica. Going to a very strong league will help him even more to become a major player worldwide.
"He's 20 years old and has a long time to play. Markovic could prove to become a very important player in Europe."
Markovic enjoyed a successful debut campaign for Benfica, scoring seven goals in all competitions as Jorge Jesus' men claimed a domestic treble and reached the UEFA Europa League final.
