Mbappe, 19, finished Russia 2018 with four goals and a single assist in seven games as Les Blues went on to lift the coveted World Cup title.
After scoring in the 4-2 victory over Croatia in the final, Mbappe equalled a second record set by Brazilian icon Pele back in 1958.
The first, a brace in the last-16 win over Argentina and the second, to score in the final of the global showpiece.
And after the final whistle, the former Selecao forward tweeted on his official account; "Only the second teenager to have scored a goal in a World Cup Final! Welcome to the club, Kylian Mbappe - it's great to have some company!"
