Almost 10 years ago, on New Year’s Day 2002, Sir Alex Ferguson believed he had finally retired from the greatest job in English soccer: manager of the most legendary sporting club of all, Manchester United. Ferguson, who had already achieved everything he could in the game he lived for, had celebrated his 60th birthday the day before. Now he was at home, taking a nap after a long lunch, when his wife, Cathy, kicked his foot to wake him up. When he opened his eyes, Cathy was standing in front of him backed by his three adult sons. “We’ve decided you’re not retiring,” she said. And that was that.
