Mbappe became the youngest player to score for Les Bleus at a World Cup when he ran onto Olivier Giroud‘s deflected shot to tap home into an empty net.
Still, France appeared to be the more dangerous team as half-time approached Lucas Hernandez had a shot blocked by goalkeeper Pedro Dallese late in the first half. Earlier, Antoine Griezmann and Paul Pogba missed the target.
Peru started the second half in similar fashion to the first, working the ball well into the final third but failing with the all-important final ball.
Pedro Aquino nearly gave the largely Peru support something to cheer when he let fly from fully 35 yards but his shot hit the outside of Lloris’ goal and spun wide.
