France coach Didier Deschamps said he was disappointed following his side's surprise 1-0 defeat to Albania, claiming the players lacked the hunger to win.
Deschamps, 46, had seen Les Bleus beaten 4-3 by Belgium at home the previous week, and then watched as the Euro 2016 hosts were shocked in Albania.
Coupled with the 3-1 defeat to Brazil in March, France have now lost three of their last four international outings, and the feel-good factor created by their World Cup quarterfinal appearance a year ago has dissipated with serious concerns being raised about the side's form.
Deschamps had severely criticised his players' attitude following their loss to Belgium -- in which two late goals gave the scoreline a respectable gloss France's lacklustre display did not warrant. And the 1998 World Cup and Euro 2000 winner was more concerned still after losing in Albania.
"With Belgium, we had an opponent that was superior to us and they played really well. We weren't as good as them," he said in quotes reported on L'Equipe.
"Against Albania, we faced an opponent with more determination and was well organised, and we didn't find a solution. I am annoyed and disappointed more than anything, because I am the first to be responsible for this. I chose the players, the systems, those who come on, go off. I'm going to take some time to analyse, but it's not a period which is very good for us."
France's shaky defensive displays, and their lack of cutting edge in the absence of striker Karim Benzema during their last two games, has given Deschamps food for thought as he considers his options for the final tournament in a year's time.
"At the highest level, nothing is acceptable," he added. "We lacked determination and aggression, that which we had and which we have lost; not in the six months that followed the World Cup, but in the last two games and above all this one.
"We weren't hungry enough. That's not acceptable, and I can't accept that. I'm not judging the players, but we weren't mentally ready to play a game at the highest level."
Renowned for his work-rate during his own playing career, the France coach admitted his squad's attitude required his attention as much as those who will actually be included in his 23-man group for Euro 2016.
"I'm not going to criticise this one or that one. I'm going to take a step back and analyse things," he said. "But whether they had five, 10 or 30 minutes on the pitch, the players have to play as well as they possibly can, and that wasn't the case."
