"I do not know whether we need to try something new against Spain," he told France Football. "We'll let the coach (Didier Deschamps) decide.
"We will work this week to become dangerous [so that we can] bring something back from there.
"I have not watched Spain's latest games but I do not think they have changed a lot of players, and they have the same philosophy of playing we know about. We know this is a very good team playing very good football and they remain the best nation."
France have won both their Group I games.
