Atletico youngster Theo Hernandez has refused to rule out a future move to cross-city rivals Real.
The left back, 19, is starring on loan at Alaves and has attracted attention from several big clubs over the past year.
Barca and Man City were among his suitors last summer, but he decided to pen a contract extension at Atleti and head out on loan to Alaves instead of leaving the Vicente Calderon on a permanent deal.
AS reports that Real, Liverpool and Marseille are among his current suitors and he has hinted that he would not be averse to a future switch to the Bernabeu.
Speaking to AS, he said: “It’s true that there were teams that wanted me but I thought about it well and the best thing was to stay.
“[Could an Atletico player say yes to Real Madrid?] I don’t know. If it’s the best thing for him, to go there, it could be that he has to go. It depends on each one.”
