Isco is battling to see out the season with Real Madrid.
The midfielder is outside the plans of Real coach Zinedine Zidane, who has approved his loan departure in January.
Real are willing to send both Isco and Marcelo away during the winter transfer window.
However, Okdiario says Isco is reluctant to leave, despite the prospect of spending much of the remainder of the season in the stands.
Isco is tied to Real until 2022.
