The Spaniard has shone this season on-loan with NAC Breda in Holland.
And local pundit Sjoerd Mossou told NOS: "That's a great footballer to watch. If I were Feyenoord I would always try for him.
"(But) I do not think he is feasible, because he is one of the few players that City does not necessarily want to sell. They really see something in him for the future, but they have to wait, because he is still very young.
"But he is truly a unique player for the Eredivisie, especially for NAC."
