Gerrard, one of Sven's talismanic figures during his time in charge, was overlooked for the current squad after a long-term groin problem.
But Eriksson insists Liverpool's skipper must go to Poland and the Ukraine next summer, even if his fitness is a doubt.

"Is he 31 already? Time flies. He must still go."
