#2 Kylian Mbappe
The best young player in the world recently completed his move to PSG after a season on loan from rivals AS Monaco. He seems to fit the mould of a Real Madrid player and he will most likely continue to be a superstar for at least the next 10 years.
Hints have already been made about an imminent move to Madrid. Rest assured, Madrid want him and they will most likely go all out to get him in 2019 should they fail to achieve reasonable success this term with the current squad. His move will likely come down to if Madrid can afford to pay the astronomical fee that PSG will demand for the 19-year-old.
