"We just stuck to the plan and it worked out well... we have been playing together for quite some time now," Dlamini said on Tuesday.
"I felt my performance on the field on Sunday was okay, but there is still room for improvement."
Dlamini relinquished the captaincy to concentrate on improving her individual game.
"The coach asked me to express myself without any pressure and I am happy things worked out more than I expected."
Dlamini, who led the women's national squad during its first-ever Olympic campaign last year, said the decision to step down as captain was difficult.
"As captain, you have to be at the top of your game all the time and lead from the front. That pressure is now gone and I am again enjoying my freedom and football," said Dlamini.
A number of young players turned out in the Banyana jersey on Sunday. Dlamini said the win would build their confidence.
"Their introduction was capped with a massive victory that should have worked as a morale booster for them," said Dlamini.
