Australia's Group C opponents have begun a war of words as Denmark coach Age Hareide accused Paul Pogba of only caring about his hair and labelled France "nothing special".
The Norwegian's side will come up against one of tournament's favourites France, as well as Australia and Peru, in Group C at the 2018 FIFA World Cup in Russia.
Manchester United star Pogba is set to play a key role for Didier Deschamps' men, but Hareide slammed the 25-year-old.
"He played against Manchester City with his hair dyed blue and white, maybe he'll have it red and white to play us," he told Jyllands-Posten.
"Does he only think about his haircuts?"
France are ranked seventh in the world and are seen as the favourites to top Group C.
While accusing Les Bleus of lacking leadership, Hareide said he had seen nothing for his team to fear.
"I don't believe in this team," he said.
"The teams at the top of the world rankings are the best in the world, but this is not the case for France.
"I saw France against Sweden in Stockholm. They are nothing special."
Denmark open their World Cup campaign against Peru in Saransk June 17, face the Socceroos June 21, and play France in the potentially crucial final group game on June 27.
