Hugo Lloris slammed France's complacency on Friday night following their 3-2 defeat against Colombia in Paris despite leading 2-0 after 26 minutes.
Strikes from Olivier Giroud and Thomas Lemar looked to have France on their way to an easy win, but Luis Muriel clawed one back before half-time and Radamel Falcao and Juan Quintero struck in the second half to give the visitors the win.
Following the match, the France captain expressed his anger at the way his team played in the last hour of the game
Lloris said: "We had a very good first 30 minutes, but after we stopped putting the effort in. We didn't do enough in the second half and showed too much complacency. I feel angry at our performance.
"We should take a good look at ourselves. We have big ambitions for the World Cup but we didn't play as a team tonight. We should look at this Colombian team. They probably have a less-talented squad than us but they are a real team.
France boss Didier Deschamps was also critical of his team and said the expectations for a World Cup contender is much higher than what he saw against Colombia.
"We had a lot of problems,'' Deschamps said. "They showed much more aggression, we did not at all. We gave away the ball to put them back in control.
"This Colombian team gave us a lesson in aggression, they would not let go. I cannot be happy, especially with the second half, but we must take time to analyse.
"We have not met the high standards we must. We have no excuses. When you lose at home it's never fun.''
Sources told ESPN that Deschamps was furious with his players in the dressing room after the game at the Stade de France, as Les Bleus suffered their first home defeat in almost a year since the one against Spain on March 28, 2017.
Samuel Umtiti, who gave away the penalty that Quintero converted, hoped the loss would serve as a lesson for the team going forward.
He said: "It is not normal to lose the game when we lead 2-0 like we did. We have to control our games better and we need the team spirit to be better. It was not good enough in the second half. We lost too many balls.
"On the other hand, we will learn from it. But I would rather it happens to us now than later."
Goalscorer Giroud said the team were lacking certain "crucial qualities" they needed to win against the world's best teams.
"We were not able to compete in terms of aggression, determination and commitment," Giroud said. "They are crucial qualities to have. We didn't have them and I don't know why. A game lasts two halves, not just one.
"We are not used to losing like this. It is a slap in the face, but now we have the opportunity to bounce back in Russia on Tuesday."
N'Golo Kante piled on with more criticism of the team's performance, calling it "embarrassing" and saying France let the Colombians steamroll them in the second half.
"Collectively, they walked on us after the break. It was embarrassing," Kante said. "We need to learn from this disappointment so we don't make those mistakes again in the future."
Colombia coach Jose Pekerman believes his side showed their preparations for the World Cup are going well.
"My team showed great character,'' he said. "This is very important in preparation for Russia.
"The first half was difficult. It is not easy to come to this stadium as the away team and France showed their best face, that of candidates to win the World Cup.
"But we understood what we needed to do to show the best Colombia team and in the second half we were better with our movement and positions to improve our confidence.''
France will travel to St Petersburg on Monday to face the World Cup hosts on Tuesday evening.
