Why don't the board listen to the manager?

Nigel Worthington talks a lot of sense, yet Delia and her chums don't take any notice of him. Back in September he told the Pink 'Un "Palace were as good as buried the Christmas that they went up with us, but they went on a tremendous run."
Remind me again, Nigel, just what was it that the Palace board did in December 2003 that ours didn't do in December 2005?
