Debuchy was drafted into Laurent Blanc's squad on Sunday night after Arsenal defender Sagna suffered a broken leg in his team's north London derby defeat at Tottenham.
Les Bleus face Albania on Friday and Bosnia-Herzegovina four days later, both games in Paris, looking to secure their place at next year's finals in Ukraine and Poland.
"I am very happy to be called up," Debuchy told www.foot01.com. "I have put in good performances lately.
"For me, I deserve it.
"There are players who are in front of me at the moment.
"Unfortunately for Bacary, he was injured. But the call-up makes me happy.
"I will give my all and see what happens."
