The Indian giants, who are currently second in the I-League, stayed top in Group H on Wednesday after an impressive 4-2 win over Tampines Rovers at the Jalan Besar Stadium.
East Bengal, along with second-placed Saigon Xuan Thanh, now look odds-on to make the next stage given they lead Selangor and Tampines by six points with three games left to play, and Barisic, who netted a clinical brace on Wednesday, believes they have an excellent chance of doing just that.
"When we saw the group [we were drawn in], we thought that qualification could really be a realistic aim and achievement," he told FOX Sports.
"We're also doing well in the Indian league and stuff so, at the moment, it's looking like it could be a really good achievement.
"The boys are looking confident and I think we've got a really good chance to qualify for the next round."
Nonetheless, the Red and Gold did have to work for Wednesday's victory given Tampines twice threatened to mount a comeback.
First, Anaz Hadee's own-goal, which had given the visitors the lead, had been cancelled out by Sead Hadzibulic's well-taken 28th minute header, and after East Bengal had raced to a 3-1 lead shortly after the hour mark, Khairul Amri pulled one back less than a minute later.
However, Trevor Morgan's side held firm and ultimately wrapped up the win three minutes from time when Barisic netted his second, and Barisic was understandably delighted at the manner of the victory and his brace.
"I'm very happy - we needed the victory and we got it," the 27-year-old said
"We worked hard but we let them equalise in the first half and, again in the second half, they returned a goal straight after we scored [to make it 3-2]. We did have to press a little harder and in the end we managed to get the fourth goal.
"It meant a lot to be to get the goals; I'm very happy. We were under a bit of pressure but to get the two goals and help us stay top - it meant a lot and I feel great."
Barisic is a new face at the club having only signed in January, but this marks the third time the Canberra native has moved to a foreign land following spells in Germany and Indonesia.
And although it's only been just under three months since he moved to Kolkata, the ex-Gold Coast United man reveals he has adapted to life in India.
"I'm liking it in India," Barisic added. "It's been a culture change and it's slightly different but you've got to adapt to it everywhere you go.
"I've been to Indonesia, I've been to other places and I've adapted to it plus the club's been amazing. I'm having a happy time there."
East Bengal currently trail I-League leaders Churchill Brothers by two points, although they have played a game extra.
