Aston Villa striker Gabby Agbonlahor is keen to follow teammates into the full England squad.
He said: "It helps you to improve your game when you are playing for the under-21s against the best young players from other countries.
"Gareth, Ashley and Scott have all been rewarded for performing consistently for Villa by getting an England call and that's what I have to do."
Agbonlahor has revealed his desire to play as an out-and-out striker if given the choice by O'Neill and he may be given that opportunity with John Carew facing a spell on the sidelines with knee ligament damage.
But the Academy product is also content to play out wide if asked by O'Neill.
He said: "Up front is my main position. That is where I want to play. If I get the chances, I think I can stick them away so you never know how many goals I could get. As a striker, you want to be scoring goals
"But I'll play anywhere for the team and I've got to learn to be versatile so, if I can play two positions, it is all for the good. If I get put on the right or left, I don't mind.
"The gaffer has been telling me to get stuck in, that I need to be like a team player really, not just getting forward but defending as well when I am playing right midfield. I think I am doing that."
