As the England captain prepares for Sunday's quarterfinal with Italy at the European Championship, Gerrard says his country's teams "haven't shown what we are capable of" in recent years.
The midfielder wants to "seize the moment" and "show our doubters and our critics out there we can compete with teams at this level."
Going into Euro 2012, little was expected of a side in disarray after Fabio Capello's resignation in February. However, new coach Roy Hodgson has unified the squad.
Hodgson cautions, though, that it could be a "very long night for us" if Italy takes control on Sunday.
