Antoine Griezmann played the main painer as France came back to life after beating visitors Finland 2-0 in a World Cup Group D qualifier on Tuesday to end a five-game winning streak.
Griezmann struck in each half after his partnership with Karim Benzema produced satisfactory results to keep the world champions at the top of the group with 12 points from six matches.
Finland, who had a good opening half, are third with five points but have two games in hand.
Bosnia are fourth with three points from four matches. They are fourth after a 2-2 draw with Kazakhstan, who also have three points. Ukraine are in second place with five points from the same number of matches.
"Even if it wasn't perfect, we showed determination and with that came some more technical quality," said France coach Didier Deschamps.
"We had more confidence, it was more like us. This is a very important result for us, now we have to finish the work in November."
After two 1-1 draws against Bosnia and Ukraine, Deschamps' tinkering paid off as France started in a normally 5-2-3 formation with Leo Dubois and Theo Hernandez as fullbacks and Griezmann. , Anthony Marshall and Benzema were in front.
But it was Finland who had their first clear chance through Urho Nisila, whose swim strike was tipped over the bar by Hugo Lloris.
Les Blaes, however, were on the attack and Lukas Herdecky put up a fine defense in the 22nd minute to deny Benzema.
Griezmann found the back of the net when he hit the ball off the outside of his foot to Haradeki on 25 minutes after Benzema collected a clever deflection into the box.
Finland continued to threaten at the break, but France proved clinical early in the second half.
After some more good work from Benzema, Dubois found Griezmann in the field and the forward snatched the ball between Heradeki and the left-hand post in the 53rd to give the hosts some breathing room.
He has now scored 41 international goals and becomes France's joint third all-time top scorer alongside Michel Platini.
Shortly after, Marshal missed Hernandez's cross, which was France's third.
France controlled the final game, keeping the ball high on the pitch and creating a few chances through Benzema, who had one night to remember his former stadium visit 12 years after leaving Lyon for Real Madrid.
