Carrick won the Champions League last night with Manchester United and Redknapp told the Daily Mail: "We brought him down to West Ham from the north east at an early age. The clubs up there didn't want him.
"He grew beyond his strength in those early days. He suddenly went from 5ft 6ins to 6ft 1in. He was like a beanpole, no strength, growing pains, problems with his knees.
"He knew what he wanted to do but couldn't get around the pitch to do it. It was a case of waiting for him to develop and fill out. Eventually he did and now he looks some player, a super passer of a ball."
