1986/87: The Souness Revolution begins

As Steven Gerrard was unveiled as Rangers manager in May 2018, he would have been fully aware of the challenges ahead of him. Without a Premiership title in seven years - including four seasons spent outside the top flight in that period - toppling Celtic from their perch was the daunting task facing Gerrard in his first managerial post.

In April 1986 another ex-Liverpool captain arrived in Glasgow to dip his toe into the murky waters of football management, charged with turning around the fortunes of the club. Three League Cups and a Scottish Cup in the 1980s were all well and good. But Rangers had not finished above 3rd in the Scottish Premiership in a decade that had seen them eclipsed by a number of clubs.

There are some football matches from the distant past that still leave you breathless when you watch them on YouTube. Matches played out in front of packed terraces, the atmosphere incomprehensible in relation to the sanitised experience of today, with both sets of players flying into tackles, as if their lives depended on it.

The 1985 FA Cup semi-final clashes between Manchester United and Liverpool are a prime example of this. Another is the Old Firm derby of October 17, 1987. An afternoon dripping in tension, the match alone was full of drama, passion, and controversy. Yet for four men involved, the consequences of their actions on that famous Saturday would rumble on for months to come.
