PFA chief executive Gordon Taylor cites Milner as proof England can grow its own talent.
Milner has amassed a record 46 England Under-21 caps, and has made it into the full team.
Gordon Taylor: "Maybe you wonder about the opportunities for some youngsters to come through and make an impression.
"But James Milner set a good example.
"He has shown his determination to eventually get to the top.
"He was a young star at Leeds and maybe at Newcastle things didn't always go smoothly, but he has stuck in there, shown his adaptability and versatility and made it to the top."
