PSG are fighting to secure Kylian Mbappe to a new contract.
The France international's long-term future at the Parc des Princes is currently up in the air, with his contract poised to expire in 2022.
With his future uncertain, Liverpool and Real Madrid have both been linked.
And Sport says PSG believe both clubs 'would pay anything' in order to secure the signature of the young striker.
Liverpool have been linked with Mbappe at a time where Mohamed Salah is being tipped to depart, with Barcelona and Real keen on Egypt international.
And Real have long dreamed of snapping him up, especially with Zinedine Zidane's side not operating at the high levels of old.
PSG could cut Mbappe loose in order to ensure they've got enough money in the bank to sign Barcelona forward Leo Messi, whose own future at the Nou Camp is also uncertain.
