Kylian Mbappé became the youngest player to score a brace in the World Cup since Pele managed the feat in 1958. At 19 years and six months, Mbappé is just 10 months older than the legendary Brazilian. It was the final when Pele managed his double, which came against Sweden, to help them seal the title.
Mbappé sent out two warning shots in the first half of France's last 16 tie against Argentina. He ran at the Argentinian defence twice and got pulled down for a penalty for one and was hauled down just outside the box on the second occasion. That wasn't his most important input though, in a game where he was the standout player. After going 2-1 down, Mbappé scored twice with a goal by Benjamin Pavard squeezed in between, to give France a 4-3 win in the end.
He also became the youngest player to score two goals at a World Cup since Michael Owen did so for England at France 1998. The future is bright for that chap.
