France manager Laurent Blanc said Samir Nasri's row with a French
journalist was bad for the image of both the midfielder and the national
team.
Nasri
lashed out at the media
after
France meekly lost 2-0 to Spain
in their Euro 2012 quarter-final.
"It is very regrettable but it's a problem between Samir and the press," Blanc told French television.
"It is very, very bad for his image but when this is done when he's with France it's also bad for the team's image."
He added: "From what I gathered, he lacked respect towards the journalist who at some point also lacked respect towards him."
Nasri equalises for France against England
His row followed reports of friction in the French camp after the defeat by Sweden in the final group game, and meant France again exited a tournament amid controversy after a player revolt on the way to being knocked out of the 2010 World Cup.
Nasri's reaction of putting his finger to his lips in France's 1-1 draw with England in their first group game against England was also believed to have been aimed at the French media.
Blanc said: "I had told him what I thought about this [after the first incident] but apparently he did not get the message."
