In previous World Cups, France have always reached at least the semi-finals after qualifying from the group phase, but circumspection has become the order of the day in the French camp this week.
While Didier Deschamps's side garnered plaudits by sweeping past Honduras 3-0 and crushing Switzerland 5-2, a much-changed team could only draw 0-0 in their final Group E fixture against Ecuador on Wednesday.
Both Bacary Sagna and Morgan Schneiderlin suggested that France were potential champions after the stalemate at the Maracana, but centre-back Laurent Koscielny has since introduced a note of caution as Les Bleus prepare for Monday's game in Brasilia.
"The first objective was to get through the group phase. Now it's to go as far as possible," he said.
"We are competitors and we are ambitious, but we know that we have opponents against us and that we might lose.
"We're aware of our qualities. Something changed after the Ukraine game, but anything is possible in a knockout match and for the moment we're only focusing on the last 16."
The Liverpool centre-back, who avoided punishment from FIFA despite appearing to elbow Ecuador's Oswaldo Minda, had to go off in the 61st minute of Wednesday's game and trained on his own on Saturday.
Yohan Cabaye will come into the team in place of Schneiderlin after missing the Ecuador game due to suspension, but Paul Pogba's place is under threat from Moussa Sissoko.
