Graeme Souness, Rangers’ first player-manager, had already built a formidable reputation as a world class midfielder with Liverpool, Sampdoria and Scotland by the time he arrived at Ibrox.

He had experienced almost everything the game had to offer, World Cups, European Cup Finals and, especially, the habit of winning trophies at Liverpool. He won 54 Scottish caps and had captained both Scotland and Liverpool.

Souness succeeded Jock Wallace in April 1986 and set about conducting a revolution.

Up to that time Rangers, despite their European Cup Winners’ Cup success, had been predominantly a Scottish team with Scottish players. Souness recognised that if Rangers wanted to be a major force in the global game of football things would have to change.

He set about breaking the mould, which included spending huge sums on transfers, capturing high profile stars with international experience such as Ray Wilkins and Trevor Francis and signing Mo Johnston who had played for Celtic.

He also reversed a 100-year-old trend of the best Scottish footballers leaving for England by enticing some of the top players in the Football League to head north of the border.

Among his captures were the England captain Terry Butcher, Chris Woods and Trevor Steven.

By changing the direction of the club in this way, Souness made it more attractive for other top names to come to Ibrox. Though at times a controversial figure, he had sent a signal that Rangers were intent on being one of Europe’s top sides.

Souness revitalised Rangers and in his first season they won the Championship and the League Cup, beating Celtic 2-1 in the Final.

The revolution gathered even more pace after David Murray, the present chairman, bought the club in November 1988 and began to make available even greater sums of money.

Two more Championships were won, this time in successive seasons (1988-89 and 1989-90), and two more League Cup Finals, with victories over Aberdeen 3-2 in 1988-89 and Celtic 2-1 in 1990-91.

It was clear that Rangers were once again the dominant force in Scottish football.

Then in April 1991, with Rangers leading the League table with just five games left to play, Souness announced that he had accepted the position of manager at Liverpool.

Although it was his successor Walter Smith who completed the job of lifting the Championship, it was Souness who had done the work and Smith himself credits the title to Souness.

Souness had pointed Rangers along a new path and after he had gone, David Murray publicly credited him with “turning the big ship round.”
