Why is Real Madrid still on the pole to sign Kylian Mbappé?

Real Madrid latest transfer window surprised everyone. One of the most powerful clubs in the world decided not to buy a single player and deal with those who came back from loans, such as Martin Ödegaard or Takefusa Kubo.

And despite earning some money after the departure of players, the income was zero. The Galacticos sold Achraf Hakimi, Sergio Reguilón, Óscar Rodríguez and Javi Sánchez and loan others to make $100 million profit at the transfer window. But then why didn't they incorporate?

Florentino Pérez is setting a strategic move that has Kylian Mbappé as an alleged. The president decided to let the transfer window pass with no incorporation in order to obey Financial Fair Play Regulations looking forward to a huge investment that they will try to make next summer for the French attacker.
Mbappé has always shown his desire to play under Zinedine Zidane mandate and, after some years at Paris Saint-Germain he also wants to make the move to Real Madrid. Mbappé arrived to PSG after the club paid more than $130 million to Monaco on July 2018 and Real Madrid will have to, at least, compensate that amount of money in order to sign him.
