Hugo Lloris wants their bittersweet defeat by Sweden to act as a wake-up call to the rest of his French team-mates.
The 2-0 loss to the already eliminated Swedes ended their 23-match unbeaten run but was enough to see them safely through to the knock-out stages of the European Championship as Group D runners-up.
But waiting for the French will be defending champions and current world champions Spain who topped Group C unbeaten.
And the French goalkeeper insists there is no time for them to feel sorry for themselves if they are to avoid getting sent home by the Spanish on Saturday.
Lloris said: "I have mixed feelings. We were playing to win but, unfortunately, we could never find the right pass. I think Sweden deserved to win.
"A positive point is, of course, the fact we have qualified, and we have to bear that in mind. We must remain positive and prepare for what will be a difficult quarter-final, a great match.
"We couldn't find the right solutions, but against Spain it will be completely different.
"It will be a great test for us, where we will have to show what we can do. We'll have to be there and end that match with as few regrets as possible."
Goals from Zlatan Ibrahimovic and Seb Larsson sealed a famous win for Sweden at the Olympic Stadium in Kiev.
France defender Gael Clichy added: "We wanted to win but we came up against a very good team with great players. We have to acknowledge that we played poorly.
"We were a bit tired because of the heat and the fact that some players have taken part in three games in [nine] days, but that goes for every team.
"We could have done better defensively and be more creative offensively. But there's nothing to worry about.
"The end of our 23-game unbeaten run is not a big deal. It doesn't change what we've achieved over the past two years.
"It means we now face a quarter-final against Spain, but if you want to win the tournament you have to beat everybody. It's going to be a great game to be involved in."
