That swagger is providing plenty of entertainment for French supporters, who were rewarded for their long weekend in Cardiff with a thumping win.
It was Wales’ smallest Six Nations crowd despite an impressive travelling contingent that boosted the coffers of the capital’s pubs.
Plenty will venture to Murrayfield with great expectations, and a little more trepidation.
“At the end when they were singing, we felt like we were in the Stade de France,” said star scrum-half Dupont.
“It’s incredible to feel that you are at home when playing away.”
A win in Lille and another in Edinburgh would give France the chance to secure an 11th Grand Slam against England.
Tandy is well placed to judge France’s qualities after a tough start to his reign that has featured assignments against the Pumas, All Blacks, Springboks and England.
“They’re in a great space to achieve that, but the Six Nations is funny,” said Tandy.
“There’s no complacency there and they are playing at a high level, so I don’t see why they can’t win the Grand Slam. They’re a formidable outfit.”
