The Lions take on Philippines at the Jalan Besar Stadium with the tie evenly poised after both sides played out a 0-0 draw at the Rizal Memorial Stadium in last Saturday's first leg.
Although he admits the Azkals will pose a stern challenge to his side, he believes they have what it takes to get the result they need to book the place in the final, and edge one step closer to a record fourth title in Southeast Asia's premier international tournament.
"I'm very happy with some areas of the first game but the job is not done yet," he said in Tuesday's pre-match press conference. "There is still 90 minutes to play.
"I'll be very happy if we show the same spirit and make the final.
"We will be playing against a strong opponent but you must show your capabilities playing against good teams. I hope tomorrow [Wednesday] we will show our strength."
One slight worry for the Serb is the fact that his side have not scored in their last three outings against Philippines, after falling to 2-0 and 1-0 defeats in two friendly meetings earlier this year.
Nonetheless, he insists he retains full faith in his strike trio of Shahril Ishak, Aleksandar Duric and Khairul Amri, and believes they cannot be bothered by their failure to break down the Azkals in previous games.
"I don't like that type of approach," Avramovic added. "That is negative thinking.
"I'm very happy [with the strikers] and I don't think there will be changes. Whether we score a goal or not is all down to the moment.
"We have to focus on the more important stuff.
"I am hoping for the same approach and attitude. In football, you cannot guarantee anything - we must do our part and whatever will be, will be.
"I just hope that the result will go our way and we make the final."
Avramovic led Singapore to two of their three previous Suzuki Cup triumphs back in 2004 and 2007.
