Despite Negri dominating much of the game, they were unable to put away the chances they created and were left to rue their profligacy when Kunanlan netted the only goal of the game in the 68th minute to hand the Red Giants all three points.
Scoring the winner against the Deer was a bittersweet moment for the Malaysia international given he had spent his whole career playing for them prior to moving to the Shah Alam Stadium in the off-season, although he insisted there was no room for sentiment on Tuesday.
"This is a dream," he told the New Straits Times. "I scored on my debut for Selangor.
"I wanted to celebrate because I rarely score goals. Although we were up against my former club, my focus was only [on] my new team.
"I wanted to make an impression and did so with a splendid strike for three points.
"This goal will give me confidence and I hope to continue scoring for Selangor."
The 26-year-old did however admit his side had room for improvement given the way they had allowed their opponents to control proceedings.
"We lost the ball rather easily in our opponents' half," Kunanlan added.
"It is something that we need to work on before our next match."
Although Selangor coach Irfan Bakti conceded his side had not been at their best, he did pay tribute to their work ethic and was encouraged by the display of new signing Francis Forkey Doe, who had a trying day in front of goal but contributed in the build-up to the winner.
"I must thank my players for giving their full commitment," he said. "We need to work on our attacking options.
"A win is a good start to the season - it was a tough match.
"The good sign is he [Doe] did contribute significantly in attack and it was his initial pass that led to our goal. He needs to be more aggressive."
Doe played for Terengganu last term and was the league's joint-top scorer with 15 goals alongside ex-Negri striker Jean-Emmanuel Effa Owona, who has since replaced him at the Sultan Ismail Nasiruddin Shah Stadium.
