A claim was made by Spain for Beşiktaş, which has been in trouble with injuries this season.
It has been claimed that the Black-Whites are considering Isco, who plays for Real Betis, and will make a move for the Spanish star in January.
Isco, who was left without a club for 7 months after leaving Sevilla in December 2022, signed a 1-year contract with Betis in July.
