Off the field, Dave Mackay resigned as manager in January 1991, to be replaced by Lou Macari on a non-contract basis. With the club in financial difficulties, Macari and his staff walked out of the club in June to join Stoke City. Many of the playing staff were out of contract and reluctant to renew, and an action group was formed to try to remove the chairman.
