Once voted our greatest-ever player by Boro fans, Souness was a vital cog in the midfield engine of the now-legendary Charlton's Champions side of the early 1970s.

A Scottish Schools and Youth international, Souness joined Spurs on leaving school and won the FA Youth Cup with the White Hart Lane club.

Growing impatient in waiting for first team opportunities in North London, he turned down Oxford to become one of Stan Anderson's final signings at Boro.

Despite a disappointing first campaign on Teesside that led to his next Boro boss, Jack Charlton, questioning his attitude, Souness blossomed into a stylish and tough-tackling midfielder that could control the pace of a game.

Benefitting from playing alongside the experienced Bobby Murdoch in midfield, Souness was voted Player of the Year as Charlton's side strolled to the Division Two title with a record points haul in 1973/74, the Scot rounding off the home campaign with a hat-trick in an 8-0 rout of Sheffield Wednesday.

A natural leader with a fearsome will to win, Souness continued to enhance his burgeoning reputation in the top tier with Boro. Liverpool came calling in 1978, and he left to join the Reds for a club record fee. 

In seven seasons at Anfield, he captained club and country, winning five league titles, three European Cups and leading out Scotland at the 1978 World Cup.

He later returned to Liverpool as a manager, winning the FA Cup in 1992, and later coached at Southampton, Torino, Benfica, Blackburn and Newcastle. More recently, Souness has become known for his punditry with Sky Sports.
