Real Madrid and Barcelona are tracking Sao Paulo midfielder Igor Liziero.
The 21 year-old has been linked with a European move to PSG this season.
However, Marca says Real and Barca are also watching Liziero with the idea of bringing him to Spain in January.
At Real, Liziero is seen as a long-term replacement for Casemiro, though would be viewed as a project player.
Tied to Sao Paulo until 2023, Liziero is rated at 2-3m.
