The Lions are 90 minutes away from being crowned champions of Southeast Asia for a record fourth time after strikes from Mustafic Fahrudin, Khairul Amri and Baihakki Khaizan helped them see off the Thais, who nonetheless netted a valuable away goal through Adul Lahsoh.
Given many installed the War Elephants were installed by many as favourites ahead of the final after a dominant campaign, Avramovic deserves plenty of credit for masterminding a commanding victory.
However, he was keen to shift all the plaudits onto his charges for winning what he believed was a thoroughly entertaining encounter.
"I think we all expected a good game and it was," he said.
"As I said before the game, these are the two best teams in the competition - Singapore and Thailand - and I think everybody really enjoyed this game. It was exciting; games like this always finish with a few goals.
"The team that keep cool and are patient will succeed in the end. I think we were that team in this game.
"The players did exactly what we've been preparing and it was a great job. Congratulations to all of them."
Despite having a two-goal lead to take into Saturday's return encounter at the Suphachalasai Stadium, the Serb does not believe the tie has been settled and insists his side must score in Bangkok.
"I must repeat that both teams are very capable of scoring," Avramovic added. "Both are capable of winning home and away.
"In some ways, we are lucky with this very good result and it's up to us now to go to Thailand and try to score. If we don't, it will be very difficult.
"We all can see the Thailand players have exceptionally good technique. They push extra people into midfield and that created big trouble for us.
"Luckily we kept our cool and our shape and all players tried to do their part as planned before the game. You must be lucky in games like these.
"This result is good for us and we just need to do it again for another 90 minutes."
While he didn't go as far as to suggest Wednesday's win was the best of the tournament so far, Avramovic did seem pleased with the way his side raised their intensity from their last match - a spirited 1-0 win over Philippines a week ago.

"I think apart from one game where we were too relaxed, the players have responded absolutely great overall," he said.
"A good example is the Philippines game [in the second leg of their semi-final clash]. The players showed great determination and teamwork, and I would say this game was a step up from that."
The 63-year-old, who is almost certain to part ways with the Lions after the tournament, also hailed the the Jalan Besar faithful and called on them continue their support.
"The support was absolutely tremendous and I hope it continues," Avramovic gushed.
"I was asked about the difference between football in Asia and Europe and I think in Asia, people should start supporting their own team. It doesn't matter who they're playing against.
"You shouldn't have 5,000 people turn up for a game against Philippines and 50,000 for a game against Japan. You have to come and support your team and that's when the players feel a lot better.
"But it was really good support tonight [Wednesday]."
Should Singapore see off Thailand on Saturday, it would see Avramovic overtake Peter Withe as the most successful coach in the history of the Suzuki Cup, as both are currently tied with two titles apiece.
