PSG only signed Neymar from Barcelona back in the summer but, despite the player being just six months into a five-year deal, the player could be on the move.
Real Madrid are determined to lure him to the Bernabeu, particularly with Ronaldo, Gareth Bale and Karim Benzema all struggling for form.
But Spanish outlet Don Balon claim the La Liga giants will have to break the bank if they are to successfully entice Neymar away from PSG.
And his financial demands are also set to leave Ronaldo reeling.
The former Manchester United star remains top dog at the Bernabeu despite failing to hit his usual lofty heights so far.
