Paris Saint-Germain chief Leonardo has slammed Real Madrid over their ‘illegal and unacceptable’ £137 million bid to land Kylian Mbappe.

But the French giants say they will not stand in the way of the former Monaco striker if the right offer comes in from the Bernabeu.

He said: “Kylian Mbappe wants to join Real Madrid and we will not hold him back. We said no to Madrid’s first offer but if our conditions are met, we’ll see.

“We’ll allow it but on our conditions. Kylian always promised us he will not leave for free.

“It seems like a strategy from Madrid to try to get a ‘no’ from us, to show that they have tried everything and to wait for a year to get him for free.”

Leonardo added: “For the last two years the behaviour of Madrid has been incorrect, illegal, getting in contact with his representatives, unacceptable, completely incorrect towards us.”
