Malaga director Francisco Aguilar has revealed interest from Real Madrid for Isco.
Aguilar told Marca that Real are keen on Isco, but a deal is still a long way from being confirmed.
"Real Madrid are interested in signing Isco, but nothing is official yet," Aguilar said.
"It fills us with pride that a lad who has come through at Malaga has become the player that he is now."
"If he leaves Malaga it will be to a big club and it will be to the benefit of the coffers at Malaga. Clubs that want him will have to meet his buy-out clause."
