France 2-1 Iceland
Group D: France 2 (Mbappe 45-pen, Barcola 62) Iceland 1 (A. Gudjohnsen 21)
Iceland made a dream start at the Parc des Princes as Arni Gudjohnsen, son of former Chelsea striker Eidur and playing alongside younger brother Daniel, put the away team ahead against France in the 21st minute.
France equalised on the stroke of half-time through a Kylian Mbappe penalty.
Mbappe turned provider as Didier Deschamps' men moved in front, racing onto Aurelien Tchouameni's ball over the top before squaring for Bradley Barcola to tap into an empty net.
Les Bleus clung on for a 2-1 success despite Tchouameni's sending off and a late effort from Arni Gudjohnsen that was disallowed by VAR.
France, World Cup runners-up in 2022, sit three points clear of Iceland in Group D, with Ukraine and Azerbaijan two points further adrift after playing out a 1-1 draw in Baku.
"We were punished for our only mistake. We created lots of chances but we are capable of doing better," said Deschamps.
