"As we all know, the team that is in very good shape is Croatia," France midfielder Paul Pogba said Sunday. "May this (opponent) be Nigeria, Argentina or Iceland, it will be still difficult."
A draw at the Luzkniki Stadium will also send Denmark into the knockout round regardless of Australia's result playing Peru at the same time in Sochi.
Although France may lack a signature win, like Croatia's 3-0 dismantling of Argentina, or a rush of goals, like eight each for Belgium and England, it is in a familiar place.
France started its run to the 2016 European Championship final with two wins. The team made a more flamboyant start at the 2014 World Cup, with 3-0 and 5-2 victories, but that campaign in Brazil stalled in the quarterfinals.
"I will get better and better," forward Antoine Griezmann told French television show Telefoot on Sunday. "It was the same at the Euros. It was only after the (second round) that I started to play very well."
Griezmann has scored one goal in Russia, the same tally he had after two games at Euro 2016, where he ended as tournament leading scorer with six.
"It's not because he did not score in the last game that he's not the same Griezmann," Pogba said. "As I already said to you before the World Cup, don't touch my 'Grizou.' Have you forgotten the last Euro? Don't play with my 'Grizou.'"
Denmark is looking to advance from the group stage for the fourth time in its fifth World Cup appearance, but coach Age Hareide will have two players unavailable to face the French.
Yussuf Poulsen, who scored in a 1-0 opening win over Peru, is suspended after being shown yellow cards for conceding a penalty in each game so far. Both judgments came after video review.
Midfielder William Kvist has returned to Russia after going home for treatment on cracked ribs and a punctured lung sustained while playing against Peru.
"It's now only the fractures on the ribs that give him problems," Hareide told Danish broadcaster TV2. "So we have to see if he's fit to train after the match against France."
