Marseille coach Didier Deschamps has urged his fellow Ligue 1 managers to unite to help the France team overcome its "disastrous" image.
The former France captain is expecting a different regime under Blanc following the difficult Raymond Domenech era which culminated in Les Bleus' dismal World Cup campaign.
"I didn't have any relationship at all (with Domenech), like the majority of my colleagues," Deschamps told L'Equipe.
"Above the fact that we know each other, that we call each other, Laurent has a different approach.
"We will adapt, we will give him information.
"This relationship between club and country is fundamental, it goes even further than the physical and medical domain.
"There are important information, this has to happen in the best way possible in a common interest, even if sometimes the interest of Les Bleus is the opposite of that of the clubs."
Les Bleus crashed out of the World Cup amid controversy as they managed only one point and one goal from three games in Group A and were left in disarray when the squad refused to train two days before their final game against hosts South Africa in protest at the decision to send Nicolas Anelka home.
The fallout from the fiasco rumbles on as Blanc has banned all 23 members of the World Cup squad for next month's friendly against Norway.
Deschamps has slammed the current mentality among the players.
"The image of Les Bleus is disastrous," he added. "What I saw there is insupportable to me.
"Certain values have the tendency to disappear.
"In my career, Les Bleus, well, it was sacred. From the first to the 103rd selection, captain or not, I knew that I was privileged."
