"When I first went to Hibs I didn't realise he was a defender but he tried to give me tips about defending," the former Feyenoord youngster told the WBA website.
"In Holland I never had those type of tips. It was more about instinct and, because I was quick, if the ball went over my head I would just run back and catch up. But I wasn't actually being told what to do.
"The gaffer would tell me about certain positions and I learned a lot from him. He changed the way I defend. I did wonder whether it would be a good thing to join Albion because I wondered if I was going to play.
"But I had had two months with the manager and even in two months I grew a lot as a defender, more than I could have under a different manager.
"As a defender I thought I could carry on growing, more under him than another manager, so that made it an easier choice."
