Mariano Diaz is ready to leave Real Madrid in January.
The striker has battled for minutes at Real since being re-signed just over a year ago from Lyon.
And Calciomercato.com says Mariano wants to leave during the winter market.
For their part, Real are happy to accommodate and would be willing to sell outright as Mariano is not in the plans of coach Zinedine Zidane.
Valencia are among clubs watching developments closely.
