Similarly, Turkey could also qualify with a victory, and the losers would have to wait another month to try again, so there is plenty riding on the clash at the Stade de France.

Deschamps told TF1: "We needed to win here and that wasn't simple even if we had several chances to score a second goal. They're always dangerous from set-pieces.

"That game was all about commitment and we lived up to that. We had a lot of the ball and we could have been out of danger with the chances we had at the end of the game.

"It's a good win ahead of Monday, an important step."

Forward Antoine Griezmann, who was fouled for the decisive penalty, said: "It was very difficult, a really hard match.

"We needed to take the three points and now we have an important game coming up at home. We're going to suffer against Turkey and we'll need to prepare well for it."

For Iceland, the result left them six points adrift of the group leaders with three games to play.

Coach Erik Hamren, the former Sweden boss, told reporters: "I'm proud of the players and the team. We did everything we could, but of course I am disappointed not to get the result.

"Proud but frustrated – that's how I feel right now."
