Real Madrid are weighing up a surprise raid on the Brazilian transfer market.
Don Balon says Real management are eyeing Sao Paulo defender Rodrigo Caio.
Real coach Zinedine Zidane is a fan of Caio and has recommended his signing over concerns regarding his defensive options going into the new season.
Caio, 23, would arrive as a direct replacement for Pepe, now of Besiktas, and will also likely see Jesus Vallejo released for loan.
PSG are prepared to compete with Real for Caio, with Neymar's presence potentially a big factor in any transfer shootout.
