The 18-year-old scored on Wednesday as Monaco beat Man City to reach the last eight of the Champions League. He was then called up to the France squad for their World Cup qualifier against Luxembourg and a friendly against Spain later this month.
Monaco took a 13th-minute lead when Mbappe drilled home after outfoxing two defenders.
Fabinho doubled the lead from the penalty spot after 49 minutes when Mbappe was brought down by Damien Da Silva.
Mbappe wrapped up Monaco’s fourth successive league win nine minutes from time with a bullet header. It was his 17th goal of the season and his 11th in the last nine games.
