I think hes reached 80% of Souness already brother. i think as an individual, Gerrard has a bit more to his game. Try and imagine Gerrard in that famous old Liverpool quartet, it would be tremendous.
I know everyone has their own opinion on these things, and with Souness being back in 78-84 era its easy to forget the great things he done for us... but I just see Gerrard head and shoulders above the rest.
