I think that King Kenny deserves the accolade as LFC's greatest ever player...I would think at the end of his career Stevie G will get 2nd spot in most peoples eyes.
Digger in my opinion deserves the number 3 spot - I saw Kenny, Souness, Hansen et al live, but not even they could generate the excitement of a Barnesy flying down the wing, or delivering a killer ball - he was an awesome player and a true gent. Had to put up with so much shit from the bitters and the press who berated him for his England games.
The team with Barnes, Beardsley, Aldo, Houghton was truly special to watch and big John Barnes was the star - awesome player !
As a complete aside, this is my own all-time 11 based on those I've seen play :-
Clemence - E.Hughes, Hansen, Lawrenson, Neal - Barnes, Souness, Gerrard, R.Kennedy - Rush, Dalglish
Subs: Reina, Hyypia, P. Thompson, Nicol, Molby, Hamann, Beardsley, Fowler, Aldo
