Turner returned to Sheffield Wednesday, who were struggling in the First Division under Peter Eustace, for a £175,000 fee in September 1988. Ironically Eustace was replaced by Ron Atkinson, who managed to keep Wednesday three points above the relegation zone at the end of the 1988–89 season. Turner played 23 of the club's 38 league games in the 1989–90 season, as Wednesday dropped out of the top-flight on goal difference. He also spent a two-game spell on loan at Howard Wilkinson's Second Division Leeds United, providing cover for the injured Mervyn Day. Wednesday made an immediate return to the First Division after securing the third automatic promotion place at the end of the 1990–91 season. Turner also kept goal in the 1991 League Cup Final, and kept a clean sheet in a 1–0 victory over former club Manchester United.
