4. Graeme Souness
Souness was the captain of the successful Liverpool team of the early 1980s and player-manager of Rangers in the late 1980s as well as captain of the Scottish national team.
He had also managed Rangers, Liverpool, Southampton, Benfica, Galatasaray, Blackburn Rovers and Newcastle United. With such vast subject knowledge and experience, he has to be there in the list even though he has been criticized few times for his punditry.
