#1 Kylian Mbappe
If Real Madrid in any way are looking for a long-term replacement for Ronaldo, Mbappe is the player they should pursue. The Frenchman is currently on a loan with PSG and an added obligation to buy next season as a result of Financial Fair Play restrictions.
The 18-year-old in his first senior year with Monaco showcased what he is capable of. Mbappe's reading of the game and composure on the ball is something noteworthy. He has 15 goals and 13 assists in 29 appearances this season.
Signing Mbappe in the very next season looks difficult. He is certainly one for the future but will come in really expensive. If the Spanish Champions manage to secure his signatures, we could be looking at an extremely talented player who could be taking forward Ronaldo's legacy.
