Gerrard accepts accusations, aimed at him in the past by Liverpool boss Rafael Benitez, that at times he has tried to be Roy of the Rovers, running around with huge energy but not always great focus.
He said: "I have tried to improve that. That was a criticism from Rafa. He's helped me to become slightly more disciplined and I feel I can play either role - either attacking or if we're up against a good side when you need your two midfield players to be disciplined, I can do that now.
"You can't afford to be Roy of the Rovers all the time against top sides. If I'm wandering off all over the place my team-mates will come unstuck."
