#2 Kylian Mbappe (Paris Saint-Germain - on loan from AS Monaco)
The only reason the French superstar (yes, he's already a superstar) doesn't top this list, is because, for all practical purposes, he's already a Paris Saint-Germain player.
The French giants signed him from Monaco on loan with an obligation to buy, thus circumventing FFP regulations following Neymar's blockbuster move to the French capital.
The youngster has seemingly shrugged away any kind of pressure that comes with being the second most expensive player in the world. He's carried over his incredible form from last season which saw him lead Monaco to a Ligue 1 title, helping them end PSG's domination.
With 4 goals and 4 assists in the league, he's formed a formidable trio with Neymar and Cavani, with his adaptability enabling to play anywhere across a front three.
Whatever tension might exist between his two strike partners, he seems to get along well with both of them, and that's a very good sign for PSG. In terms of numbers, it might be the marquee names of Cavani and Neymar hogging the limelight, but Mbappe's performances indicate a maturity way beyond his age.
He won the Golden Boy award this year, and already has 10 caps for the French national team. His 3 goals and 3 assists in the UEFA Champions League also show that he's devastating against virtually any kind of opposition.
He's already broken the record for the most number of goals by a teenager in the UEFA Champions League, and the kid's not even 19 yet. He's a central figure for arguably the best team in Europe right now, and he's only going to keep improving.
