Chelsea midfielder Mason Mount values his time with Vitesse Arnhem last season.
Mount has now joined Derby County on a season-long loan.
He told the Daily Mail: "I gained a lot of experience being out there and hopefully I can bring it into this season.
"I learned a lot out there so it is going to help me.
"Obviously, that was my first season playing professional football so anything you gain from playing is going to help. This year I will get even more experience playing in the Championship."
