Odegaard will spend the new season on-loan in the Eredivisie.
He told Voetbal International: "My father and I have regular contact with the Real people.
"They watch my matches in replay and sometimes someone comes to Heerenveen to see me. Now it is time for me to make further progress.
"I would like to take advantage of this year to become a more mature player and return to Spain a better one. My main objective remains the same. It's imposing myself and finding my place at Real Madrid."
