Malaga have warned would-be suitors that they will not be dropping their asking price for Spain U21 international Isco.
Isco has a clause in his contract which requires interested parties to put £30m on the table before discussions can begin, and vice-president Moayad Shatat says that fee will have to be matched if one of Spain's brightest young stars is to be on the move this summer.
"He's a magnificent player, very important to us and if the offers do not match what we are looking for then we will not sell the player," Shatat told reporters at the unveiling of new Malaga coach Bernd Schuster.
"We will only sell for the right price, and that price has been set.
"We have no need to sell if the price is not right."
