#1 Kylian Mbappe - 20 years (PSG)
Future Ballon d'Or winner in waiting? Kylian Mbappe has undoubtedly been the standout young player in the world over the last two years, with his performances catapulting him from being a little-known teenager at Monaco into global superstardom.
Mbappe's achievements at such a tender age are well documented so it would be futile to repeat them here, but it suffices to say that the World Cup winner has had a career at 20 that a majority of footballers throughout history would have been proud to have had.
The now 20-year-old has already made a mark on this tournament following his displays with AS Monaco in their fairytale run to the semifinal in 2017, but would be looking to go one further by leading PSG all the way to their holy grail.
With Neymar, Edinson Cavani and Marco Verratti all sidelined for the marquee clash against Manchester United, Mbappe would carry extra responsibilities. However, on evidence of what we have witnessed so far, he has the shoulders to carry the extra burden and United would do well to keep him in check as the prodigy has the key to unlock any defense.
