France defender Lucas Hernandez said his teammate Kylian Mbappe could become world's best player if he continued to play the way he did in the World Cup round of 16 match against Argentina.
France beat Argentina 4-3 in a pulsating encounter in Kazan on Saturday and will move through to the quarter-finals, while Argentina were eliminated from the tournament.
Mbappe scored twice and earned his side a penalty, which was converted by Antoine Griezmann.
"Mbappe has a good future if he continues playing this way," Hernandez said. "He will become the world's best player.
"Today Mbappe was very good. Argentina's experience did not help them today. We are younger and it helped us to adapt to different situations during the World Cup more easily." Hernandez told journalists.
In the last eight, France will face Uruguay on Saturday (12am AEST).
