I think in that team he didn't much need to. He was a hell of a player and as you say, possibly the best of his generation I can only think of Matthaus coming close around the later stages. But then, this is not that generation, and the game has changed, it's faster and we are currently not the top dogs and are still a great work in progress - the team Souness played in was a polished engine that only needed occassional tweaking. In that instance, I think Gerrard's ability to change a game is more profound as the team around him (until recently) has not been that great.
