Notable events
Rangers won their third league title in four seasons under the management of Graeme Souness.
Aberdeen won their first major honours since the departure of Alex Ferguson, winning a cup double of the Scottish Cup and the League Cup.
Celtic finished the season without winning a trophy, mounting the pressure on manager Billy McNeill.
Rangers abandoned their longstanding signing policy by acquiring Mo Johnston, who was the first high-profile Catholic player to sign for Rangers. Johnston joined Rangers after having come close to rejoining his old club Celtic from French club Nantes. Also arriving at Rangers was the Everton and England winger Trevor Steven, filling the gap on the right wing left by club hero David Cooper, who signed for Motherwell.
