Real Madrid president Florentino Perez is under no illusions over the cost to bring PSG star Kylian Mbappe to Spain.

The France World Cup winner is a 2020 transfer priority for Florentino.

And Okdiario's Eduardo Inda, speaking on El Chiringuito, says the president knows it will take world record money to convince PSG to sell.

He revealed: "Real Madrid wants to advance the signing of Mbappé next summer.

"They have made calculations and the amount would not fall below €300m."

However, it's also claimed if Mbappe signs a new contract tabled by PSG, then Real will abandon the move.

A Madrid source told Okdiario, "If Mbappé renews, he will be tied the PSG for life and it will be impossible to get him out of there."
