France are ranked seventh in the world and will enter the World Cup as one of the favourites.
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."
