Gernot Rohr's men will face the French island team at the Stade Francois Coty in preparation for next month's Africa Cup of Nations qualifier against South Africa.
"I know a bit about them when I was here in France. Most of their players play in the Ligue One so I expect a tough challenge from them," Echiejile told theNff.
"We cannot afford to, and will not underrate them."
Echiejile also lauded the healthy competition within the Super Eagles' rank, saying: "The team is improving after every game but there are places in the team the coach thinks to need more competition which to me is a welcome development.
"Every good team needs a good backup and I think that is what has informed the reason for the new faces in the team for these friendlies."
