Speaking about the Dutchman to the CT, Coleman said: "He's only a baby and to make your debut against one of the strongest teams in the Championship is not easy. But his attitude was fantastic - he was so calm on the ball.
"He's very attack minded and he was caught out playing too wide for their goal. We'll work with him on that, remind him he has got to defend as well as go forward, but it was a great debut for the kid."
