Kylian Mbappe struck twice as France saw off bogey team Denmark 2-1 to book a place in the World Cup knockout stage.
Mbappe, outstanding in France's opening Group D victory over Australia, was the star of the show again with two close-range finishes - his winner coming four minutes from time.
Denmark, who had beaten France twice in the Nations League this year, fell behind after 61 minutes but soon levelled through Andreas Christensen.
Mbappe's double puts him alongside Pele as the only players to score seven or more World Cup goals before their 25th birthday.
The victory extended defending champions France's World Cup winning streak to six games.

What is France’s World Cup record?
France are defending champions, having beaten Croatia 4-2 in the 2018 final at the end of a near faultless run, including victories over Argentina, Uruguay and Belgium.
That was their second World Cup victory following the Zinedine Zidane-inspired triumph, when he scored twice in a 3-0 battering of Brazil in the 1998 final.
However, it was arguably the great midfielder’s head-first assault on Marco Materazzi and subsequent sending off that cost his side in the 2006 final, which Italy went on to win on penalties.
France boast some of the most talented players in the world and possess a particularly fearsome attack. They should ease through their group yet, while it would be unwise to rule them out of winning it again, France have a history of implosion on the international stage. Additionally, no team has managed back-to-back world titles since Brazil in 1958 and 1962.
