He said Lady Cathy, who he married in 1966, wanted no sign of his glittering life in football in the house.
He said: "My wife, Cathy, is fed up with the whole thing. When Alastair Campbell phoned her about my knighthood she said to him, 'Do you not think he's had enough rewards?'
"You'll not find a thing about my career in the house at all. She's unbelievable. I can't even take a football book home or she'll say, 'What are you doing with that?"
The former Aberdeen boss added: "I prefer to think about what's ahead and what next I can achieve, and I think that has kept my feet on the ground quite well. I've never got carried away with it."
