Bobby Robson was replaced at Ipswich by his chief coach, Bobby Ferguson. Ferguson made the transition from coach to manager in July 1982, but some success in the various cup competitions was offset by an end to the high league positions the club had enjoyed under Robson. In the three seasons from 1982–83 to 1984–85, Ipswich reached the FA Cup quarter-final and League Cup semi-final in 1985, but declined in the league, finishing 9th, 12th and 17th. In the following season, the team's league form was even poorer, resulting in a 20th-place finish and relegation to the Second Division. Ipswich finished fifth in the Second Division in the 1986–87 season to qualify for the play-offs, but Ferguson resigned after losing to 2–1 on aggregate to Charlton Athletic.
