O'Neill said: "Should Ashley get a call up? That's not really my decision but I think he's a fantastic footballer whose time will come. He's had a great, great season for us and the England manager has come pretty often to see him.
"I'm sure at some stage or another he will give him that opportunity and I think Ashley will shine."
Young, who struck in Villa's 1-1 draw with Bolton, added: "I have my fingers crossed I can get myself back in the England squad, but I have to concentrate on Aston Villa first."
