Manchester United boss Sir Alex Ferguson admits he was mistaken in selling Jaap Stam to Lazio in 2001.
"I made a mistake there, no question. It had nothing to do with the book. The problem was Steve McClaren and I thought he had lost a yard of pace after an achilles operation.
"Then he had a bad start in the first game of the season and Lazio came in with £16.5million, which was a lot of money for a 30-year old centre-half. After he joined Lazio, I went to see him and he was fantastic. So it was a bad decision. Too hurried."
