Yet on Sunday, five minutes injury time bit him in the knackers ... and that self-satisfying look that has dogged the Premiership for 20-odd years was wiped from his smug face.
"They've scored," came the cry and Ferguson replied: "Get them off the pitch! Get the players off the pitch!"
A dramatic end ... and I'm sure 99.9% of the country laughed their socks off.
And STILL he had to have the final word!
Sir Alex Ferguson: "They [City] can go on as much as they like. That's what you would expect, but the history of our club stands us aside.
"We don't need to worry about that. I think we have a rich history, better than anyone, and it will take them a century to get to our level of history."
