At 19 years and 183 days, Mbappe became the youngest player to score for Les Bleus on soccer's biggest stage.

And his reward was leading France into the round of 16 with a 1-0 victory over Peru on Thursday.

"I've always said that the World Cup is a dream for any player," Mbappe, who was born a few months after France won the 1998 title, said.

"It is a dream come true and I hope I will have more like this."

With two wins from two matches in Group C, France are through to the next round with a match to spare. Peru have been eliminated. Denmark are on four points after their 1-1 draw with Australia left the Socceroos on one point.

Paul Pogba, one of France's best players, set up the 34th-minute goal

He beat his defender and play in Olivier Giroud, whose shot took a deflection off a defender and looped over goalkeeper Pedro Gallese, allowing Mbappe to tap in from point-blank range.

France coach Didier Deschamps made a pair of tactical adjustments after an underwhelming performance in the team's opening win over Australia.

He started Giroud and Blaise Matuidi but kept the same 4-3-2-1 formation.

Paolo Guerrero started for Peru after coming off the bench in the opening loss to Denmark. He came out with energy but he cooled down after receiving a yellow card in the 23rd minute.

Guerrero nearly missed the World Cup before his doping ban was lifted by a Swiss judge prior to the tournament.

France goalkeeper Hugo Lloris - who played his 100th international and 76th as captain - was one of three opposing skippers, along with Australia's Mile Jedinak and Denmark's Simon Kjaer, who signed a letter to FIFA supporting the lifting of the ban.

Guerrero had one of Peru's best chances in the 87th minute from a free kick but his attempt went right at Lloris.

"We gave it our best in two matches. We came into this match with a completely different set of expectations but I have nothing to hold against my players," Peru coach Ricardo Gareca said.

"France is a hard team to harness. ... France corrected its style over the course of the game, this proves that France is a great side."

Peru will face Australia in Sochi while France take on Denmark in Moscow, both on Tuesday, with top spot to be decided and the second group qualifier.
