France defender Patrice Evra remains bullish of their chances of success at Euro 2012 this summer despite their sluggish performance against Iceland.
Iceland are ranked 115 places below France but that did not stop them from racing to a two-goal lead.
Mathieu Debuchy and Franck Ribery netted the goals to bring France level before Adil Rami's late winner for Laurent Blanc's team.
For a team tipped to succeed at the European Championships, the French would have been expected to sweep aside such opponents easily.
But Evra believes his country will improve and be a force at this summer's tournament.
"We must not be too hard on ourselves," Evra told L'Equipe.
"After one match, you cannot know exactly what you need to do to improve. The second match is different, the third as well.
"You can play very well in your warm-up games and lose the first match at the Euros. It is June 11 we must be ready for."
It appeared that Evra was at fault for one of Iceland's goals but the Manchester United defender pointed out, it is the responsibility of the team and not just individuals to keep out goals.
He added: "When we concede goals, it is down to everyone. We should not single out the defence, the attack or the midfield."
