Move aside, Lionel Messi and Cristiano Ronaldo.

He’s only 23-years-old, but it looks like Kylian Mbappe is ready to assume the mantle of the best soccer player on the planet.

He reminded the world of how devastating he can be in France’s 2-1 victory over Denmark at Stadium 974 in Doha, Qatar on Saturday.

Mbappe scored twice, including the game-winner in the 86th minute of the Group D encounter to propel the defending champions into the knockout round. The French (2-0-0, 6 points) defeated Australia, 4-1, in its opener.

Denmark (0-1-1, 1) must defeat Australia (1-1-0, 3) in its final group stage match after the Socceroos edged Tunisia (0-1-1, 1), 1-0, hoping that the northern African side doesn’t upset France.

Mbappe, who has tallied an astounding 14 goals in his last dozen international matches, began his personal showcase in the 61st minute, when he put away Theo Hernandez’s feed for a 1-0 lead.

Andreas Christensen knotted things up for the Danes in the 68th minute, opening up a path for Mbappe’s late-match heroics.

He scored an exquisite header from close range on the left side after a pinpoint cross by Antoine Griezmann from the right flank to snap a 1-1 deadlock. The young striker is tied with Ecuador’s Enner Valencia with three goals apiece for the World Cup scoring lead.

Mbappe, who stars for Paris St-Germain, has scored 29 times in 60 international appearances. At the 2018 World Cup in Russia, he scored four goals as a 19-year-old as he won the best young player award of the tournament.

In the final day of Group D play, France, which is trying to become the third national team to win back-to-back World Cups, meets Tunisia on Wednesday while Australia takes on Denmark.
