Real Madrid tried to sign Kylian Mbappe from PSG during the summer transfer window but the French giants refused to let go of one of their prized assets.

Los Blancos president Florentino Perez has lamented his failure to lure the winger to the Santiago Bernabeu during an interview with Spanish publication Marca.
There were multiple reports containing diverse figures alleged to be how much Real Madrid offered to pay PSG for the signature of Kylian Mbappe. Perez has now confirmed the real figure to be around €200 million.

With PSG refusing to sell Kylian Mbappe, Real Madrid are reportedly waiting for the attacker’s contract to expire in June 2021 and sign him as a free agent.
Florentino Perez hinted at the same and also fired shots at PSG and other state-owned clubs.
He continued:

PSG managed to keep Kylian Mbappe at the Parc des Princes during the summer but the game is still far from over. Real Madrid still believe they can lure the attacker from the French capital and will surely not give up.
As the player himself recently revealed, he is keen on joining the Spanish giants. In fact, his move to the Santiago Bernabeu is a matter of when and not if.
With the privilege of deciding his next destination after running down his contract at the end of the season, the winger will get the chance to follow his heart. It remains to be seen what choice he’ll make.
