Mike Catt says France arrive at Twickenham on Saturday as a "wounded animal."
France arrive on the back of two shock defeats, away in Italy and at home to Wales.
And Catt, England's skills coach, says 'Le Crunch' on Saturday evening will be an "exciting" challenge for Stuart Lancaster's young team.
"We lost against Australia and South Africa (in November) and then came back to beat the All Blacks - France are in the same position," Catt said.
"They are a wounded animal, they are a very proud nation and they enjoy playing against the English. It is a big one at Twickenham.
"As a team we have grown. We showed a lot of maturity in that Ireland win.
"They will probably throw something at us that we haven't experienced before. It is about how quickly we adapt to it and the players have done exceptionally well on the field, making those decisions and coming up with solutions.
"It is massively exciting and a massive learning step going forward."
Skipper Chris Robshaw added: "For us it is the next challenge.
"They come to Twickenham on the back of two losses. We have been in the situation where people start to write you off and they will come here and give it a real go.
"Defensively we have to be switched on because the French can play from anywhere and that element of surprise is what they bring.
"We have looked all week on how we can improve on the Ireland game and hopefully tomorrow we can take that into the game. We are in a good place."
