France kick off their Six Nations tournament at home to Italy with last year's defeat in Rome fresh in the mind - and Dusautoir believes Italy's showing in the World Cup where they ran Australia close demonstrates they are not to be taken lightly.
"Italy lost to Australia at the World Cup (in the pool stage) but were on level terms at half-time against a team who scored 60 points against us the year before," said Dusautoir.
"This is not the Italy of a few years ago. Last year we lost to them but it was only logical after the progress they have made.
"We are going to approach this match knowing how important it is to win the first game, and for a win in Paris in front of our supporters."
