Vitesse coach Van der Gouw: Buttner desperate for success at Man Utd
Van der Gouw made 60 appearances in six seasons with United, and passed his experience onto his young compatriot, who is champing at the bit to make his mark at Old Trafford.
"He's so excited about joining United," he told manutd.com. "Having got the chance, he really wants to go for it. He was very impressed with what he saw of Old Trafford when he went to sign, even though it was empty. I know the feeling.
"I told him he was very lucky to be arriving at a club like United, because it's a totally different world to any other club, and I told him to take the chance with both hands. I really hope he does."
