#5 Kylian Mbappe - AS Monaco
The most obvious replacement, yet at the same time, the most improbable signing this summer. It seems like Kylian Mbappe is destined to sign for Real Madrid, whether that is this summer or in the future. He certainly won't come cheap - AS Monaco will demand the world (and more!) for arguably the most promising player to emerge since Neymar.
Take a look at the money Real Madrid have raised so far - Pepe and Coentrao have been taken off the wage books, while the loan and sales of James Rodriguez, Mariano Diaz, Diego Llorrente, Burgui and now Alvaro Morata have raised €106 million so far. With another €30-35 million expected from the sale of Danilo to Manchester City, Florentino Perez could have €140 million to work with.
This is not a man to leave money lying around - Florentino will go big - he's already copped plenty of criticism from the fanbase for the sale of Morata. The only way to appease them? Bring in a player who was involved in 44 goals in 59 appearances at the age of 18.
