Real Madrid are seeking to clear €70 million worth of talent off their books.
So far, Real have only sold Ezequiel Garay to Benfica for €5.5 million, with another five players still available.
Pedro Leon (€10m) and Royston Drenthe (€14m) are being offered to clubs across Europe.
Lassana Diarra (€20m) and Fernando Gago (€20m) are still to attract firm offers this summer, while Sergio Canales (€5m) remains available on-loan.
