The Montpellier central defender is confident of adjusting to the rigours of international football after breaking into the national side under Didier Deschamps
The Montpellier defender just missed out on a place in his country's Euro 2012 squad, but after responding to that disappointment he is hoping to adjust to the rigours of international football.
"It was tough. The opponent were smart and aggressive. I have experienced this level now, but the worst is yet to come," he told RMC Sport after the 1-0 victory over Finland on Friday night.
The 23-year-old partnered Mamadou Sakho at the heart of the back four in Helsinki, and he believes further experience will only improve their partnership.
"We must continue to be successful and raise our game gradually," he added.
"This was [mine and Mamadou Sakho's] second match and we tried to work better together. We communicated and gave a lot of information.
"We agree on and off the field. After [international duty], he plays in Paris, I play in Montpellier. But outside, we try to ask questions."
