The island nation defeated Burundi 1-0, courtesy of a 76th-minute free-kick from Marco Ilaimaharita in their second Group B game.
After seeing off the “tough” challenge from Burundi, Dupuis said he is pleased with the team’s hard-fought victory as they edge closer to securing a spot in the last-16 round.
“I am so happy because of this victory. It was our first in the history of the Afcon and we worked hard for it.
“It was not an easy match because Burundi gave us a tough time especially in the second half.
“But we can be proud of our efforts, we can be proud of what we achieved but the work is not yet over. We still have Nigeria to think about,” Dupuis said after the game.
Madagascar are second in Group B with four points after two matches, two points behind leaders Nigeria.
They face the Super Eagles for their final group fixture in Alexandria on Sunday.
