I think its different to that. I think that sometimes people who are truly gifted find it hard to understand their gifts. Its why many good managers were only modest footballers - they had to understand the game so much more, and know what players needed to do to improve. While other players, such as Mat le Tissier, probably have no idea how they did what they did. (
What a player he was btw).
Fergie won 5 of the last 7 titles. And we were inches away from the other two - goal difference and an offside goal. That's unreal and makes it hard to criticize him. My guess is that he thought that he was just a hard working Scot, and that the squad was winning so much they were obviously good enough. He probably thought another hard working Scot would do. He probably wasn't totally aware that he had some sort of unnatural aura that made players play out of their skins.
