The England youngster concedes he's unsure if he will be returning on-loan next season.
"First finish the playoffs. Then I have the European Championship with England Under-19. And then a new season follows in the summer. I really have no idea where that is," the attacking midfielder told Der Gerlander.
"The Eredivisie is the best thing that happened to me. It is technically well-coached. In this area I have taken steps again this season.
"In professional football, everything revolves around profit and loss. That creates much more emotion than a competition in the academy.
"I always stood out in the youth and reserves of Chelsea. That was automatic. At Vitesse I learned what fighting is. Everyone has to fight for his place. I have learned to live abroad. With a language barrier. Far away from family, friends and my girlfriend."
