Kylian Mbappe and Gianluigi Donnarumma have both verbally committed their futures to Real Madrid, but it remains to be seen if the two 18-year-olds will arrive at the Estadio Santiago Bernabeu this summer or next.
Zinedine Zidane will be the one to make that decision and he has a meeting with Florentino Perez in the coming days. The fact that Los Blancos' squad is already packed full of star names means he could look to avoid adding another two into the mix prematurely and unnecessarily.
It should be noted that both players' cases are slightly different, with Mbappe still sitting with two years on his Monaco contract, while Donnarumma only has one year remaining at AC Milan.
The French forward is excited to work with Zidane, but the coach would still have to convince him that he would earn enough playing time though his squad rotation if he were to make the switch this summer.
If the coach and the player agree to make the transfer happen during this window, then the fee would likely be in the region of 100 to 110 million euros - which is a short of the 130m euros the Ligue 1 champions are asking for, but which is expected to be sufficient.
As for Donnarumma, he has just 12 months left on his contract and Real Madrid could wait until the summer of 2018 to sign him without having to pay a transfer fee, but with the risk that he might change his mind and sign on some other club's stationary.
The other option would be to purchase him now, with 30m euros to 35m euros likely to be enough for AC Milan, given the player only has a year left on his deal.
For Los Blancos, that figure would be similarly satisfactory, as they know that Donnarumma could be their shot-stopper for the next 15 years or so. In the end, it will be Zidane who decides when these two starlets make their way to the Spanish capital.
