Rangers became founder members of the Alliance Premier League but this coincided with the club finishing low in the league, as various managers found it difficult to follow the success of the seventies. After four seasons Rangers were relegated to the Northern Premier League. This form continued, but with the appointment of Ron Reid as manager during the 1983–84 season as manager the club soon began to rebuild its reputation and won the 1984–85 League title. Back in the Alliance, the Bob Lord Trophy, Jim Thompson Shield and Staffordshire Senior Cup were all won within two seasons. During the late eighties and early nineties, Rangers struggled in the Conference, with six managers in seven seasons following Reid's departure in May 1988. The sale of striker Stan Collymore to Crystal Palace in December 1990 for a substantial six-figure fee stands out in this period. Under the management of Dennis Booth, Rangers enjoyed a tremendous 1992–93 campaign. In the league they finished 6th and reached the FA Cup Second Round, defeating Lincoln City in a First Round replay at Marston Road.
