Alex Goode has insisted that England must respect France when the two sides clash in the Six Nations on Saturday.
Stuart Lancaster's side enter the match at Twickenham having won both of their opening two matches, but France have suffered back-to-back defeats.
"They are unpredictable, but they have got a lot of quality players who play in top sides, who are going well in Europe as much as their league, and we have to be at the top of our game," the Saracens fly-half told Sky Sports News.
"They have had great results in the autumn, they won all three games, so they are a good side and we have to be very wary of them."
England are the only team still capable of claiming the Grand Slam.
