Down below he had a 23-strong backroom staff, that took up half the Milburn Paddock!
And all for what?
He would have been better off with a cloth cap, a whippet, a copy of the Sporting Life, and call himself "Billy No Mates", for what difference it would have made to his long ball tactics.
Keegan is now turning his mind to deciding who to keep from the 23 backroom staff he inherited.
Allardyce had a huge number of specialists working with him and Keegan is expected to tell many of them that their services are no longer required.
Asked if he had made a decision on his backroom staff, Keegan, who has brought in his old assistant Arthur Cox, added: "Not yet. My first priority now is to see if we can get players in."
However, long-time buddy Terry McDermott is certain to stay.
