He is a player that Madrid supporters would want to see, whether or not the Portuguese stays or goes.
It seems half of the elite sides in European football have asked about the young Frenchman and it's no surprise, because the Monaco striker wants to be one of those players who define an era and his numbers at this point indicate that he can do it.
He is only 18 and a half years old and is better, statistically, than Ronaldo was at the same age.
AN IMPROVEMENT ON RONALDOM
bappe is beating everything that Cristiano Ronaldo achieved at the same age.
The Frenchman officially debuted as a professional aged just 16 years and 11 months whilst the Portuguese was 17 years and six months old when he played in the Champions League.
A first official goal against Troyes in the French league came at 17 years and two months for Mbappe, Cristiano achieved it at 17 years and eight months against Moreirense.
Where he really is overtaking Ronaldo is in the Champions League.
The Portuguese didn't get his first goal in the top European competition until he was 20, while Mbappe already has six - achieving the first at 18 years and two months at the Etihad Stadium against Manchester City.
The young star is one of those players who only appear in the footballing landscape from time to time.
He has 60 matches as a professional - two of them with the national team - under his belt, while Ronaldo had played only 31 at the same age.
Mbappe was also three months younger when making his international debut.
A European U19 title last year was followed by the French Ligue 1 crown with Monaco, in a season where he was second top scorer with 15 goals.
If the Portuguese leaves Madrid, Mbappe would definitely explode and become, for many, the best player in the world.
The Frenchman can make the leap to any one of the great European teams but everyone knows Real Madrid is the team he dreamed of playing for when he was a kid.
Mbappe is a prodigious footballer and there's some certainty that he will try to reach similar heights as his idol Ronaldo.
