Paris Saint-Germain will reportedly demand the services of Casemiro if Real Madrid make an approach to sign Neymar this summer.
The Ligue 1 champions currently find themselves fighting to keep both Neymar and Kylian Mbappe at Parc des Princes, while also looking to strengthen ahead of next season.
However, there remains the possibility of the former being sold if the price is right as speculation mounts regarding a potential return to Barcelona.
Real Madrid are also said to be monitoring the situation, but Marca claims that PSG will only consider a deal if the Spanish giants allow them to have Casemiro in part-exchange.
PSG are looking to secure a replacement for Adrien Rabiot, who is expected to move elsewhere on a free transfer in the coming weeks.
The report adds that Real boss Zinedine Zidane may consider a sale if it boosts their chances of signing Paul Pogba from Manchester United. body check tags ::
