France defender Mathieu Debuchy is hopeful that his side can defeat Spain next Tuesday but admits that it will not be easy to do so.
"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.
