A terrific midfield player and a true leader - Graeme Souness.
Signed from Middlesbrough in January 1978 for a fee of £350,000, Souness would go on to be one of the club's great leaders.
The Scot had a reputation of being a no-nonsense midfielder who wasn't afraid to throw himself into a tackle - but he made his mark in front of goal with the strike named goal of the season against Manchester United in the same season.
He would end the season at the heart of the Reds' midfield, earning his first European Cup winners medal as the Reds successfully defended their crown in 1978 with a 1-0 win over Club Brugge at Wembley.
It would be the first of many trophies for Souness, as he was at the heart of one of the greatest Liverpool sides in the following season that lifted the League title.
More success would follow in the League Cup and in Europe. Midway through the 1981/82 season, manager Bob Paisley felt there needed to be a change of captain. Souness would be the recipient of the armband, succeeding Phil Thompson, only a matter of months after winning the European Cup in Paris against Real Madrid.
In 1983, when it was well known that Paisley would be stepping down as Liverpool boss, Souness insisted that Paisley should lift the League Cup after a triumph over Manchester United at Wembley.
The following season would be the last for Souness as Joe Fagan reluctantly entered the managerial hotseat, but the Scot would leave his mark as the Reds won a treble of the League Championship, the European Cup and the League Cup - the latter of which was secured courtesy of a remarkable Souness strike in the replay against Everton at Maine Road. He was certainly one of the most remarkable Liverpool players, making 359 appearances for the club, scoring 55 goals.
He left the Reds to head to Sampdoria in the summer of 1984 - winning the Coppa Italia in his two year spell - before returning to the UK to be player/manager at former club Rangers in Scotland, and would have success
His return to Liverpool as manger wouldn't have the desired effect. Souness suffered from heart problems during the 1991/92 season and his stock fell considerably despite winning the FA Cup as Liverpool's decline was apparent at the start of the Premier League era. Liverpool fans were also furious over an interview he gave to The Sun - a publication that is still hated and boycotted on Merseyside to this day for their coverage of the Hillsborough disaster. He admitted he should've resigned there and then.
Instead it would be an FA Cup defeat at the hands of Bristol City in 1994 as he was succeeded by Roy Evans.
He would have limited success elsewhere, winning promotion to the Premier League with Blackburn Rovers in 2001, winning the League Cup 2002 and helping to re-establish them in the top flight, but a subsequent spell at Newcastle didn't have the desired effect.
Now, Souness can be found offering punditry and analysis for Sky Sports.
