Now 30, time is running out for Gerrard to make a significant impact at a major tournament, which is something he needs to do if he is to be recognised as being world class.
The Reds midfielder said: "All the players in this squad recognise this is the stage where everyone wants to prove that they can be a top player.
"I have shown signs that I can do it at this level by scoring goals and putting in decent performances.
"But can I perform consistently in every game at a major tournament? That's what I'm aiming to do.
"Physically I am in great shape. Mentally I'm fine. I'm chomping at the bit and I can't wait to get going.
"But the important thing is that we do it as a group. We don't want players being too individual and thinking about themselves.
"The only way we are going to deliver at this tournament is if we are together and we are strong as a unit."
